I know this is a long read, please bare with me, as I not only am reviewing the Yoobao battery but also, providing some information on batteries in general and how the G1 battery works (read post 11).
A few days ago I got a Yoobao 2400MAH battery on ebay for $25 shipped. Here's my little review so far after a few days of use.
Background: I'm an avid RC flyer. I own electric powered and gas powered planes and have done a lot of work with Lipo and Li-ion batteries and have applied the same things I've learned from there to any and all batteries.
Few things I've learned is never let a battery drain to it's bare minimum. I've read numerous times that one should let the battery die all the way and charge it all the way and let it die again. For Lipo and Li-On, 80-90% drain is ideal before recharging again. I'll continue with this later. This does not apply to the G1 though, just a general pointer. Read post 11 to see why this does not apply to G1.
Now on to the battery.
The battery comes with the the extended cover. Which has a nice rubbery feel to it.
The battery came with the charge at 70%, which is nominal for shipping and storage. i got it and plugged it in and charged to to max. I then used it through out the day and right off the bat, it was performing wonderfully. By the end of the day, I still had 60% power left, when normally, I would have drained the stock battery by now. I did not charge the battery that night (Monday night) and by morning still have 50% charge. I charged it when it was down to about 15%, a full charge took about 2.2 hours. Which sounds about right, assuming the wall charger was providing 1Amp constant, the 2.2 hours of charge time equates to about 2200Mah of charge.
From a full charge, I've watched a 2 hour long movie, gtalked, SMSed and it has drained about 40% (60% remaining).
It is typically offering twice the length then my stock battery was, Though I've had it 3 days, I will continually update this thread.
i do have the tools and equipment to measure the charge this batter takes in So I will do that tonight and report my findings. I plan to drain the battery to 15% and charge with my digital charger and see how many MAH it takes in. I expect it to take in minimum 2000mah at 85% discharge.
So far, I give it a thumbs up especially at $25.
My brother has the seido 2600. I will test that as well.
Pointers:
Conditioning the Li-on battery by draining it to 0% and recharging and then draining to 0% is rather harmful to the battery. Lipo and Li-on cells do like going below 3.0-3.2V. The Nominal Voltage of the cell is 3.7V, a fully charged cell is at 4.2V-4.25V or so. Dropping it below 3.0V cause more harm to the battery then good. (Again this does not apply to G1)
Try to avoid draining the battery all the way if you are not able to charge it. Most phones have a cut off point, and my guess is for the G1 battery, it's 3.2V, or I hope it is (actually, it's 3.5V as you will read about it in post 11). But you use the phone to where it cuts of, and are not able to charge the batter for a few days, then that could drop the voltage to below 3.0 (over time). I've seen people do this when they use multiple batteries, and end up killing all of them because they let them sit while fully discharged. Big no no with Li-ons.
LI-on doesn't suffer from memory loss , charge them whenever possible. They do how ever become uncalibrated. Meaning if you constantly plug it in at random discharges (which is perfectly fine), the state of charge may differ from the actual charge gauge. Simple problem to resolve, Drain the battery too 3.2V ( I will post if draining the battery on the g1 to 0% is 3.2V or not) and fully recharge.
More numbers on the Yoobao, Seido and stock batter later.
Thanks for the info. I was a little taken aback when I read about this "drain it all the way" advice too. I just got my g1 and I'm still on the stock battery. I'm curious to know what you find.
Thanks for posting.
Very good review man. I hope this one doesn't get merged with that big o battery thread. This one actually has information coming from someone that knows their stuff.

I moved it here, and placed that warning.
Sorry about that, I totally overlooked the accessories section . I was wondering why no one was replying lol.
Anyways, I still can't do the test because I'm waiting for the battery to die! I charged it yesterday morning, Since then I have turned t he brightness at 75%, been using it at the gym, browsing the web, and was on the phone yesterday for atleast 2 hours and was on gtalk last night for a about an hour. Then left the phone on all last night (though in standby).
I do have wi-fi and GPS OFF as I don't use it, it is working 3G.
Currently I'm at 46% so Still waiting for the thing to go down to 15%. Maybe I can finally drain it down today and test it tonight.

That's the first time I'm hearing about someone waiting for their battery to die Good review
very good review .im glad your reviewing the 2400 and hope fully 2600. i am getting ready to buy one or the other ,i know the is a big price diff. between them.cant wait till ya update this thread
Alright so Last night I finally got the battery down to 9%. I've got some interesting findings.
Few more things I'd like to point out before presenting some numbers.
Background on battery ratings: Batteries are rated in mAH aka Milliamp Hour, or how much power/charge a battery will hold. How is this measured? I won't go into details so will just give a run down version of it. Batteries are rated from their lower cutt-off voltage to the maximum voltage. The lower cut-off voltage for Li-ion and Li-po is 3.0-3.2V (3.2V being ideal).
The mAH rating is the amount of charge that it took to take the battery from 3.2V to 4.2V. In the Li-ion case, the lower cutt-off is 3.2V, the Nominal voltage is 3.7V and the maximum voltage is 4.2. Anything under 3.2V is over draining and anything over 4.2 is overcharging.
Why do I bring up the above? to give you an idea of how these batteries get rated.
Often companies will rate their batteries from a lower cut-off point to have HIGHER CAPACITY RATING. For example, if I Charge a li-ion cell from 3.0V to 4.2V, it will take in extra capacity as opposed to if I charge it from 3.2V to 4.2v, It just looks good on paper and spec sheet. This happens often. same with AA rechargeables, the lower cutt-off range is usually 1.0V but often companies will rate from .9V to achieve higher numbers. You will never see this disclosed on the battery, you'll just see the rating. (It will never say Capacity 1800mAH from .9v) etc.
Again, what's the point? There are a couple of points.
1) The G1 NEVER drains the battery down to 3.2V. It's cut-off point is surprisingly 3.5V. I do not know the specifics, perhaps the G1 cannot operate below 3.5V.
This means that even though the phone is dead, the battery still has some juice in it, just not enough to power the G1 or it may be enough to power the G1 but the power management of G1 is not allowing it.
The stock G1 battery which is rated at 1150 mAH, is only being used down to 3.5V, which means you're only using ABOUT 800-900 mAH of it's capacity before phone shuts off.
2) This Yoobao battery is surprisingly, very well rated. At 9 % power, It was still reading 3.6V. REMEMBER: that's 9% till the 3.5V cut off. The battery was most likely rated at 2400mAH from 3.2V! When I hooked it up to my li-ion charger, I was able to push in roughly 2000mAH. so In other words I rate this battery 2000mAH from 3.6V. Yoobao rated it 2400mAH from likely 3.2V. And I would conclude that the rating is accurate and not over inflated.
CONCLUSION: You will never use the full capacity of the battery just because of the way the G1 is designed. It will always cut off at 3.5V. The good thing about this is you will never over drain your battery, so you can run your G1 to the dead point as many times as you want as you will never go below 3.5V. Nice feature but I'd rather have it go down to 3.2 so I can squeeze that extra power out of the battery (Wonder if this could be software modified).
TWO THUMBS UP!!! to YOOBAO 2400mAH battery. Priced at $25.
Some rough numbers:
Stock 1150mAH : 850-950 useable mAH
2400mAH: 2000-2100 useable mAH
2600mAH: ASSUMED 2200-2350 usebale mAH as I have not test my brothers seido yet.
Any questions, I'm happy to answer them.
*I'm in no way shape or form related to the manufacturer of any batteries, I'm just a regular consumer who bought the extended battery and decided to review it since it's rather a new product.

Im considering getting this new batttery is the phone a lot thicker in the hand, could yoy post photos ? cheers
i was thinking of getting this for my girlfriend instead of a mugen power one like i have but i just wanted to know about the battery cover this comes with.
my mugen has these little plastic cone things that go to the camera lens and speaker phone to help keep crap from my pockets from getting all the way inside and it helps with speaker sound, so my question is does this battery back have anything like that or is it just hollow or something?
thanks
Some pictures as requested. I would save the two pictures where I'm holding the phone with both hands and just go back and forth on those two just to get a idea of how thicker it got.

I will try to get my hands on my brothers battery, he has the 2600. I will have to give him mine. He's deaf and has to have an extended battery so I will do the swap when I see him this week.
Cheers for the photos thats sealed the deal for me, off to ebay to sort one out
i wouldnt try the batt if it come from china...
coz there are alot of problems with batts from china....
i.e. battery explosion
Thanks for the review - best one I've read on here, sounds like a good battery.

You do realize that almost all the batteries come from China, right? It's possible to get decent products from there - just because it's "Made in China" doesn't mean it's automatically crap. Need to read reviews, use common sense, etc for something purchased from anyplace.
Hate bidding. I wish there was a "Buy-It-Now" on this item. It's gonna be kinda cool leaving my home and not having to worry about my phone dying.
Edit: Got outbid on Ebay last night. Battery went for $33. Glad I lost. Just order the same one on Ebay with a buy it now for $19.50. I wonder how long the shipping is from China?

Hello everyone,
Getting my G2 tomorrow ad was wondering what's best to do for the initial charge ?
What did you all do and how do you find your battery because of it ?
Cheers James
hi there mate
I did a 3-4 hour charge until the battery was fully charged...the orange led charge thing goes green and its fine then
right now im managing to get a day with heavy use, which is good
Thanks immya
Any other advice please ?
I atcually do the same. But i repeat the process of fully charge and discharge the phone completly about 2-3 times. So the battery gets well trained. I repeat ist about every 2 months. I know it should not be relevant with those new batteries, but i found out it is, and the battery last longer.
jut my 2 cents
Cheers,
Chaos42
it's 2009, just charge it and use it.
when i got mine the battery was ~1/3 full, i charged it till ~2/3, then had to leave and completed the initial charge like two hours later, all works fine, getting somewhat between 4 hours and 3 days of usage.

Hey chaos42
What do you mean should not be relevent with the new batteries ?
Is there some sort of new batteries with the newer phones ?
Thanks
James
no, what i meant was what immya just said. that with the modern Li-Ion batteries you should not worry to much about how and when to charge. I just wanted to add that even it is 2009 i observed a far better battery lifecycle and stamina when you try to take care of your batterie. and charge it as decribed. that's my experience. at least for the initial 2-3 charges.
cheers,
chaos42
not that i am trying to discredit you here (in fact i would be very interested in such numbers myself), but did you do any tests or comparable setups to check the difference? because if we are talking about "a feeling" that you have this is IMHO not really relevant data. i would like to see two identical phones in a (at least) similar environment, performing the same tasks the same amount of time a day, and with that getting different runtimes on the battery for a period of a few weeks. these two phones don't need to be heros necessarily, as long as they have the same type of battery and can produce comparable results, but as long as this doesn't happen i myself rely on the tone on li-ion batterys in general. which is (and i am not able to quote or prove this): they are robust in terms of regular charging, and worrying about wearing the batterys in or training them isn't worth the effort. again no discredit here, but as long as no comparison has taken place there is effectively no data to analyze... just too much variables.

NiCad batteries work best when fully discharged before re-charging otherwise you get what is called the memory effect. If you are in the habit of topping up before being fully discharged the better 'remembers' how much you let it drain before charging it and then get's the idea somehow that this is what its capacity is and goes flat at the point that it 'expects' to be recharged.
NiMH batteries are much less prone to memory effect. They are the ones that need the 16 hour first charge then subsequent charges are shorter.
Li-Ion - lithium to its friends - are not supposed to suffer any memory effect at all. You are supposed to be able to top up as and when you want without any detrimental effects.
None of the above batteries will last forever and will need replacing after 2 or 3 years of daily use.

Absolutely spot on!
These days batteries do not require dishcharging fully before recharging. Even if the person in the phone shop says "ensure you charge it for 12-14 hours before you use it", this doesn't matter - once the battery is fully charged, it stops charging itself anyway - even if you leave it plugged into a charger!
Same as what's being said already.
To add, it's even better to keep your lithium battery topped. Fully discharging them is actually bad for a lithium battery. Full discharge and heat is what's bad for a lithium battery.
For a nice reference, check this: http://electronics.howstuffworks.com/lithium-ion-battery.htm
(the life and death part is what might interest you)
On a more interesting note. A long long time ago I got a MDA Compact aka Qtek s100. And there was a lot of debate here on the forums about the initial charge. In the manual it was stated that you should charge it for like 12 hours or something the first time. Then people obviously also said that was bull, because it had a lithium battery.
But! As for WM2003 it didn't save it's whole registry etc on the ROM but in the RAM. Once the battery was dead, bang! hard reset right there.
So they included a little NiMH battery in the s100 that would keep the RAM 'alive'. And that was the reason it needed such a long first charge, for the NiMH cell.
And for some reason a lot of manufacturers take an 'old' manual text for the first charge of a battery. Although that doesn't happen that often anymore. Especially in the beginning a lot of instructions of how to use a lithium battery were just plain wrong. And they put NiMH or even NiCad instruction in there!
Edit, some instructions as found here (http://www.batteryuniversity.com/parttwo-34.htm). Talks about laptops, but it's the same nonetheless.
Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.
Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level.
Consider removing the battery from a laptop when running on fixed power. (Some laptop manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the battery. For best results, store the battery at 40% state-of-charge.

To get the best battery life, when should I charge my phone? When the phone almost runs out of juice, or whenever I can (below 80%) ? Please help!
Deep discharges are bad, but so is spending lots of time at maximum charge.
I'd consider charging around when you hit 80% if it's convenient, but if you're expecting to be on battery for a while soon, top off whenever you want.
Discharging to 5-15% is bad for your battery longterm.
So to get the best battery, I should charge when it is $80 right?

There's no hard fast rule about 'exactly' when you should recharge it. Simply try and keep the phone from running < 20% a lot and never keep it always charged at 100%. If you get in the habit of charging in the 30-80% range, that would be best.
Basically throw out the old mentality of always using it as much as possible before recharging as lithium batteries simply don't work like the old nicad batteries from years past.
This phone uses a Li-Ion battery, and these batteries do NOT have any kind of "memory." Charge it whenever you want to. However, it's not really good to always keep it "topped off." (Deep discharges are also not good.)
If you are going to store the battery, drop it to 75%-50% charged first.
There are some things to consider, however:
If the phone's power circuit bypasses the battery when the battery is fully charge (instead of constantly pulling power from the battery while the battery is recharging), then leaving the phone plugged in is better than constant charge/discharge cycles. Based on the fact that this phone will work properly with NO battery attached when plugged in, this is probably a true statement (but I can't know for sure.)
Second, the phone itself might like to see the battery charged/discharged once in a while to calibrate the battery monitoring circuitry. (You never calibrate a li-ion battery - only the circuitry that monitors the battery.)
Here's a link with some interesting information:
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Take care
Gary
Got it. Thanks for all your information
A small note to add why you shouldn't 'keep' it above 80% (constant top offs and being left on the charger). In general when above 80% it's been found that lithium ion batteries have a 'higher state of activity'.
What that does to the battery is what it sounds like. Higher state of activity means higher wear and overall shorter lifespan.
That wear is easily seen in laptops. Many people have the habit of leaving them always plugged in while using and through the night, so they're always 'ready to go'. People who consistently do this to their laptops usually find after 1 year the battery life is noticeably shorter, 1 1/2 years 50% or so of 'new' capacity, and after 2 years looking at replacing the battery.
And I usually find a cheap deal on eBay for them, plus $50-75 for me. At least phone batteries are a bit cheaper.

Just gonna review some of the accessories I have used and what i think about 'em
First up is the 3500mAH extended battery by HHI
This battery came in at a cost of $9.99 with free Shipping! It showed up with an 80% charge which is in the acceptable range of where they like to sit. The battery performs just as one would expect it too. I am currently running MeanRom, and can easily get 16-20 hours of use with some really heavy gaming. However I recently went on a vacation and wanted to run the battery through a couple different variations of "discharging". So with the phone in Airplane mode(no radios connected) and very little use i easily can get a week out of the phone without charging. Again this is without any radios on, not connecting to anything.The stock battery cant touch these numbers. i would be lucky to get a full day out of the stock battery with no gaming and normal use.I didn't do a sticker pull to run the numbers. So I'm taking HHI's word on the 3500mAH being just that.
To conclude on this battery the $10 investment turned out to be a good choice, although it might not be a seidio or something it does more than i expected it to do. I will continue to use this battery till I get rid of the phone. The battery can be found here.
To continue on the batteries,
I also bought some of the Galilio "2000mAH" batteries, I got 3 of them with a wall charger for $13.99 on ebay, as reviewed by many others.
This is my experience with them. So they showed up in the mail and upon opening them i discovered one of the batteries look like it got dropped or skipped accross the cement, im not sure what happened, but who is gonna put a messed up battery in their phone.. So i really only got 2 batteries. I brought it up to the seller he offered me $3.00 back, it wasn't worth my time even dealing with that any further at this point. Anyways the batteries Are nice little backup batteries i take with me on trips.They make for easy backup batteries. The batteries have been suspected to be somewhere along the lines of 1000-1200mAH. I would have to agree, even with no testing with any type of tool, besides my phone. They last a most couple of hours. The wall charger that came with them actually surprised me. Everyone was reporting that it may overcharge your stock battery, which can cause some issues. This charger(as pictured below) will charge the Galilio batteries to 100% with no problems. I put my stock HTC battery into the wall charger and with repeated attempts the charger will not charge the battery past 85% even when i left it on the wall charger for 2 days. I do believe that the stock HtC charger that came with the phone gives the batteries a "better" charge, but the wall charger seems to not charge the batteries past a safe range as everyone seems to be reporting as a possible issue. My issue is it doesn't charge it well enough.
I've attached some pictures of the battery results and of the batteries.
Reserved for more... case reviews coming up next
i got the 3500 mAh from HHI. great battery, even better price.
Yea that battery is awesome!

Going to try this battery out. Thanks for the review.
The 85% is charge limit is what a cheap charger do,
The "charger" that come with the phone is simply a power supply, the charging circuit is actually "built in" to the phone. You can connect the OEM HTC charger/power supply into one of those cheap aftermarket dock that charge a 2nd battery and it will never charge the battery past 85% either.
To make it short and sweet
There's 2 stage of Li-ion charging
1) charge to 4.2v at constant current which is 85% when it first reach/near 4.2v
2) saturation charge, once the battery reach 4.2v, continue charging but at gradually reducing current until it reach about 3% of default charge current
Cheap charger have a simple/cheap circuit and cannot do stage 2 charging, where the charging circuit built into each phone would do stage 2 charging

After having the Moto 2nd gen for a day I'm pleasantly surprised at the battery life. On my 1st gen Moto I usually got just under 10 hours of battery with the ambient mode on. My 2nd gen has been on for over 20 hours and the battery is down to 46%. The screen has been on the whole time except from midnight until I put it back on this morning. This may be a new feature whereby the Moto can detect if it is being actively worn or just lying on a desk at night.

Overall battery life has been stellar on my 42mm Gen2. My only issue with it is that at or shortly after it hits 15% it shuts down automatically and won't turn back on till it's charged up for a couple minutes. basically I don't get the last 15% of the battery. I exchanged my first unit and this one does the same thing. I've had it for 4 days now, and going through a few full charge cycles hasnt changed anything.

I've not had a smartwatch before so the rate of decrease is a little alarming for me. I can still get through a day no problem though - perhaps I could even stretch it to two if it's fully charged in the morning.
What disappoints me is the speed with which it recharges. Since the battery is tiny, I assumed it would recharge within an hour. Instead it seems to charge slower than my HTC One M7, which is notorious for being the slowest charging phone of all time.
Never owned smartwach, impressed by battery life
I bought the 46 and for 3 full days never ran out of battery and and 20 to 30% left at bedtime, ambient on wrist gestures off.. i am playing with it like mad so it will even get better i assume.. but loving it
Only on my first day, but so far battery is far superior to original Moto 360 and even rivals my LG G watch R performance. With ambient on, and moderate use (emails/text/weather) I am seeing 3% battery drain per hour (8.5 hours use with 74% remaining).
I will give a more thorough update once I have spend a few days with it.
Odd my 46mm is at 22% and it has been about 12 hours. Seems a bit short compared to what you guys are getting. Granted I have all the features turned on (ambient display, gestures, etc) It is my first full day with the watch. I'll see how well it does tomorrow maybe just the first drain needs to calibrate the battery.

I don't have a graph for it but having it on from 10 to 10 (12 hours) mine went 100 to 71% surprised the hell outa me considering the day before was 80 to 30% in about 4-5 hours granted that was with setup and fiddling with apps and whatnot. If it didn't make such a damn nice little nightstand clock I'd have just left it sitting for the night. This is with ambient on gestures on wifi auto and all the heart monitor junk off on the 46mm model.
I got 44 hours out of mine yesterday with ambient on and gestures off. I'm still observing the screen going off if the watch is just lying around somewhere. Funnily nobody else seems to be mentioning this.
How did you turn off the heart monitor stuff? I didn't see any options for this either in fit or moto body. Even checked the android wear app and the connect app. I do see it is checking heart rate at least once an hour or more at times, and just checked it and found it checking every 5 minutes now.
Want bad the other day checking every hour still got 2 days use, but noticed it last night and today when the battery was only going max a day.
Day 2 of battery. About 12 hours and it is at 38%. Ambient and gestures on. Curious as to what you guys are doing for substantially better battery life. I am going to try turning off ambient tomorrow.
i think it would be better if you mentioned the model you have since the battery is bigger in the 46mm model
I have a 46mm Moto (400mah battery). I use 3rd party watchfaces and run ambient (always on), auto brightness, and receive approx 40 emails and a dozen text messages in a normal day. I don't use tilt to wake as I can always see the watchface in ambient, and wifi is off. I pulled off the charger this morning at 7:15am and now at 11:30pm I am at 47% approx 3.6% drain per hour. Have had the watch now for 4 days. This rivals the performance I get out of my LG G watch R. Must say I am very happy with battery life so far.
Can anyone with a 42mm tell me how the battery is with ambient off and gestures on?
Wow, I have had the 46mm watch for two days and both days it had died by 1pm after pulling it from the charger a 3am, not even close to 12 hrs
I do use it with endomondo for about an hour in the morning but still, have ambient turned off. Guess I'll try turning off the gestures and see if it might last a day.
My best day with the 46mm was the day before yesterday. Took it off the charger around 9AM on Monday. Put it back on charge around 9PM on Tuesday. Ambient On, Gestrues and WiFi off. Still had about 20% left but had to charge it for the next day. BTW my 46mm Moto 2 charges just fine with the first gen charger.
My batter life goes from horrible to ok for no reason.
Last night my watch hit 100%charge at around 1am. I took it off the charger and set it on the table. I just over 4.5 hours it was under 25%. Using Wear Battery Stats I see no app activity, and the screen states watch is "Off".
I charge it back up when I got up to 52% before I went out on a 1+ hour workout using endomondo, listening to audible. Both applications were showing on the watch when I check (distance for endomondo and play controls for audible). This only took it down 9%.
This makes no sense.
Think I need to contact customer support or just return it as defective?
Thanks
I have heard that lithium batteries have the best life span if you don't let them discharge too far. For example, a battery put on the charger more frequently - say 50% - will last longer than one where you wait unil 20%.
This comes from the RC helicopter community where they monitor battery life and performance pretty closely. I'm wondering if anyone knows data about this with watches?

What you mention is a good guideline for maximizing battery life. Linked below is a great article I commonly come back to and share out to others regarding lithium battery life.
The advice I usually give is to "fully" discharge the battery once per initial setup or factory reset, and then fully charge it overnight. This will give the OS a good handle on the upper and lower charge parameters to properly report available battery percentage. Most of the onboard controllers for batteries keep them from getting too close to fully charged or discharged, so regardless of what's being reported to the user. The user only needs to be concerned with this middle area they have to play with since they'll never see the "full" capacity of the battery. but even though we never see the "full" 300mah or 400mah, we see the same middle area of each, so from a comparative standpoint these numbers are still valid to extrapolate relative available capacity. if that makes any sense.
Anyways, the short version is that most smart devices already manage the charge cycle pretty well since most smart device users are just dumb users. So if we calibrate the batteries we use with a full charge and discharge cycle, then just use the devices like dumb users, we're probably just fine.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Interesting article, and accompanying links. I believe they are saying the same thing as the RC helicopter folks - don't overly discharge, do frequently recharge:
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses.

It's fun to see "how long you can go" without recharging, but it might not be the best practice.
Hello guys,
I'm willing to buy the 46mm. We always talk about autonomy of smartwatch but I'd be interested to understand what affects the battery of the smartphone in% after a full day always connected Bluetooth?
I have a Note4 but I would not lose too much autonomy.
Thank you in advance

Hi,
OneUI 5.0 and previous one also introduced protect battery that doesn't allow u charge phone above 85%. I am using it often because for me it dont affect my phone usage patterns. I can charge phone at least once per 8h and it is almost impossible to discharge phone in time (I have S23+ but I am posting here cuz its more active tag). I am leaving house at 80% and coming back at 50% in overtime scenario.
But also I read it is healthy to full discharge (or till 5-10%) and then full charge phone at least once a month and some sources says even more frequently to do it.
On one side rumours says u should always avoid discharging under 25% and charging over 80%, and other says u should relatively frequently discharge ur phone and then charge it up till full.
I want to know how it works in theory I am not interested in getting answers like "lol man why u even care, phone is for you not otherwise" - because it is often answer in topics like that.
I think that charging to 85% with low speed will be more than enough.
I saw with my gf phone, hauwei p30 pro.
I tried so hard to "teach" her a proper charging routine, but she just doesn't care. The only thing I managed to do is silently enable the "smart charging" to stop charge battery under max capacity.
After 3 years honestly her battery life is still great, as it was mine with the regular Huawei p30 (me, a maniac as you).
Anyway, if you really like the phone, you can afford replace battery after 4 years (should be even cheaper with s23 ultra)

I am using 20W to charge my S23+ so it is not slowest charge but not fastest aswell. Still alot slower than chinese products offering 100W+. I think charging from 20 do 80 in like 35-40 mins is really healthy for battery.
My problem with replacing battery is more that it is hard to find original one and find service that can replace it without losing data and other stuff. At least I had much problems with it with my previous phone but it was realme not samsung so I am aware after 2 years I will have problems with replacing it.
Minimize the current drain. Higher current drain reduces the battery's life span by requiring more full charge cycles for the tasks but also by raising the operating temperature.
Avoid starting a charge cycle below a battery temperature of 72F, 82 is better. Keep charging temps below 102F. 82-99F is ideal.
NEVER attempt to charge a Li that's near freezing temperatures.
Li's prefer frequent midrange power cycling rather than longer usage/charge times. My typical cutoff is 40% or higher and 72% if I'm trying to extend the battery life. Ideally it should be allowed to "settle" after a charge before using.
Never charge with the display on.
When the battery reaches 80% of its new capacity it's considered degraded and should be replaced. Degraded cells are more likely to fail. Any swelling is a failure, replace immediately. A failed Li can damage the display.
I totaly abused my note 10 plus from september 2019 to february 2023, so almost 4 years - charging to 100%, connecting/disconnecting whenever i needed it, playing games while charging everyday, draining it to 0% sometimes, other times it was on 92% or 87% and i was planning a long day, so i charge it to 100%, full abuse. My battery was in perfect condition till the day i bought the s23u. I think that the quality of the battery matters much more than the way you use it, your usage patterns have very little effect on the battery in the period you use your phone. Maybe if we start using our phones for 10-15 years, it will matter, but...
I don't do the stop at 85% on my devices but I do turn off all fast charging and I'm happy with that, but that's just me.
1) Don't put your phone on charge and sleep 10 hours.
2) Keep your charge between sweet spots. %40 - %80 is always ideal.
3) Fast charging does not harm.
4) Don't play games while charging.
5) Don't let your phone get too hot. Hot battery die sooner.
I use default 25w oficial charger from Samsung S21 Ultra, i have like 4 of those and i see no point in having a 45w to shave 10mins of charging time. Fast charging enabled.
I also made a routine, on Saturday and Sunday it disables battery protection so it charges 100% for when i travel and use camera a lot, during work days battery protection(85%) is enabled by default.
I have my S23U 1080p 120hz using light mode all the time and i'm having good results.
in my life I've had a lot of smartphones and what I can say is that I've never performed these types of charges from 25% to 85% and I've never had a problem, however where I had problems was with smartphones that had a processor badly optimizing the heating prevents the battery from working properly and above all the cables and chargers if you use non-official chargers or damage your battery, there is a risk of damage
From what I read it does not matter if you charge to 100 % but you should not continue charging it.
To prevent this I just made a routine that turns on the 85 % mode as soon as it reaches 99 % (I guess I could've chosen 100 % but did not...). Then it stops charging and I wake up with around 99 % charge..
Try to not go below 30% and never ever go to 0 or close to it. Li Ion battery are fragile in deep discharge as same li polymer batteries. So never go in deep discharge, it makes more damage to the battery than charge it to 100%. I have 10y lipos batteries for my RC models that i never go below 30% and they still have 95% of capacity... 10y and running fine in hard condition RC helicopters that pulls all the battery to 30% in 5 minutes. Li ion are the same...
Why not play games while charging? Isn't also supposed top have power passthrough?

Well probably it is because gaming = heat and chargin = heat. Double source of heat may cause battery damage. This is probably the only reason.
Battery University has a really good article on what causes excess battery damage.
Basically, after manufacturing, the battery will get damaged even if it just sits there. But the things to really look out for:
Don't leave the battery discharged
Avoid heat
Don't charge when the battery is cold
Don't charge when the battery is hot
Fast charging creates heat
Don't charge/discharge above a rate of 1C
Don't keep the battery at a high voltage (fully charged)
So keep the battery between ~30-80% at a reasonable temperature
Since my first smartphone (a BlackBerry Curve) I've charged my phone's to 100%, left them on the charger all night, and plugged in in the car. I've never seen a noticeable degradation of battery life. I know it happens, but I think it's been blown out of proportion.
What's the point of a big battery and great battery life if you ly charge it to 85%? I think by the time the battery actually reached the point that it only had the equivalent of 85% health/life you'll be long ready to trade it in.

If you plan to hold it for at least 4 years its worth saving battery. And i believe this is the phone i'm going to hold for a long time. And like i said before, using routine for weekends at 100% battery.
This is me today at work, from 85% to 71% in 10 hours, 35min sot, with 4 calls less then 5min each since i'm at work i can't use my phone all the time. 1080p, 120hz, ligth mode. wifi and bluetooth enabled with watch honor magic 2 connected.
I know it's in Portuguese but you can understand by icons and stuff.

To save battery for max you should always have from 50 to 70% charge from 10C* to 45C* do not use phone lower or higher degrees it may cause bad reaction to battery. Do not use fast charge all this stuff based on a lot of researches you can find it.

Ok, if you're going to keep it that long I can see trying to maintain the battery. I do trade in yearly, but in that year Ive never seen any degradation. And I do all the things you're not supposed to. It stays in my car on the charger in the heat and the cold. I leave it charging all night. I abuse TF out of my battery. The rest of the phone I keep pristine tho, LOL.
I don't worry about battery at all. I love fast charging option and it's always on. I need the phone to charge fast, even though Samsung's 45W is actually really slow today. Why I don't care? Because my 2 years warranty covers the battery issues too (2X per year) so I can ask them to exchange the battery if the condition degrades.

Agree, fast charging is just too convenient. I do limit top charge and discharge % though. On this heavily used N10+ I expect about a 2 year battery lifespan. Battery change outs aren't that hard or expensive. It's going to be on its 3rd battery soon. The first one had a hard life because the phone wasn't properly optimized the first few months; constant high current drains will kill the battery prematurely.
