Pants - is the only way to describe that post, false info.
It does no harm at all to fully discharge, more problems are caused by giving regular, short charges, than 1 long full charge so i wouldnt believe that.
He also says to charge it 8-10 hours, that total rubbish as well, these batteries dont need 8-10 hours to prime, on average 3-4 hours for a full charge is more than adequate.
I think few year back batteries were far inferior and did indeed need longer charging periods, but not any more, and if ya flash roms a lot and need to calibrate your battery after flashing to a new custom rom indeed part of the calibration process is completely running down the battery, my s2 is well over a year old and has been drained flat many a time and i still get 14 - 20 hours out of it on average, which is damn good for any smart phone these days, That post is on a HTC Thread by the way, Htc notoriously have batteries with a crappy life span, i had a wildfire s, used to get about 6 hours out of the battery.
I don't think that's true.

Hmmmmmm, no, you didnt start the thread, i was replying to the starter of the discussion, not yours.
More importantly, where is your link meant to point, coz from what i can see it only points to a google search and not to any specific document, unlike donalgodon who posted a very interesting and intriguing link indeed with so much info

Mine was a rhetorical question, but it's all good, dude.
Lol, short version: Depending on the battery type you will want to drain it completely before charging or never drain it completely. Let it charge fully overnight or it only needs a few hours.
Seriously, do some reasearch on batteries. Figure out what types there are, how they are different, and what makes them different. each has advantages and disadvantages.
Every battery type is a little different. For our phones will be different than for your rechargable nicad batteries at home, or the batteries in your remote control vehicles.
Bottom line: We COULD tell you, but that would be defeating the purpose. Instead we are pointing you in the right direction to acquire the knowledge yourself. Happy hunting! let us know how it works out!
In simple, it actually causes more harm discharging the battery to empty.
There is alot of do's and donts to preserve the battery,
Info:
The Li‑ion charger is a voltage-limiting device that is similar to the lead acid system. The difference lies in a higher voltage per cell, tighter voltage tolerance and the absence of trickle or float charge at full charge. While lead acid offers some flexibility in terms of voltage cut‑off, manufacturers of Li‑ion cells are very strict on the correct setting because Li-ion cannot accept overcharge. The so-called miracle charger that promises to prolong battery life and methods that pump extra capacity into the cell do not exist here. Li-ion is a “clean” system and only takes what it can absorb. Anything extra causes stress.
Most cells charge to 4.20V/cell with a tolerance of +/–50mV/cell. Higher voltages could increase the capacity, but the resulting cell oxidation would reduce service life. More important is the safety concern if charging beyond 4.20V/cell. Figure
Discharging:
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.
Battery manufacturers ship batteries with a 40 percent charge. The low charge state reduces aging-related stress while allowing some self-discharge during storage. To minimize the current flow for the protection circuit before the battery is sold, advanced Li-ion packs feature a sleep mode that disables the protection circuit until activated by a brief charge or discharge. Once engaged, the battery remains operational and the on state can no longer be switched back to the standby mode.
Do not recharge lithium-ion if a cell has stayed at or below 1.5V for more than a week. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. If recharged, the cells might become unstable, causing excessive heat or showing other anomalies. Li-ion packs that have been under stress are more sensitive to mechanical abuse, such as vibration, dropping and exposure to heat.
And may i point out, this is a community, People ask questions and peoples feedback, the web is not always correct and nor is the information you find.
It takes more effort to argue with someone and to point someone in the right direction, instead of just answering there question.

Indeed, not everything on the web is correct.
But may I point out that all you did was copy and paste text from this page, which donalgodon linked in post 4, and again, I feel I must point out, was actually one of the results in the Google search I linked him to.
The point I was trying to make, and seems lost on you, is teaching people how to look for stuff on their own. No one should just expect to be spoon-fed information. That is lazy to just post a question on a forum, sit back, and watch the answers roll in. You should do your own legwork and research.
As the old adage states: give a man a fish, and you feed him for that day. Teach a man to fish, and he is fed forever.
hey
i readed that li-po battery is better then normal battery
maybe there a battery that could fit to rezound and work with it ?
https://www.sparkfun.com/products/8483
maybe this could be modded and fit to rezound ?
It's a complicated issue and there's not a clear cut "better" technology. They're both better for different applications. In practice, Li-Po hasn't proven itself to be any better for mobile phone applications than Li-Ion. It's theoretically safer due to the higher resilience to overcharging, and it's able to be made thinner due to the dry electrolyte, but the overall energy density is lower, so you'd get less power out of the same battery size, and they don't last as long as a standard wet electrolyte Li-Ion.
http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
Lithium-ion-polymer has not caught on as quickly as some analysts had expected. Its superiority to other systems and low manufacturing costs has not been realized. No improvements in capacity gains are achieved - in fact, the capacity is slightly less than that of the standard lithium-ion battery. Lithium-ion-polymer finds its market niche in wafer-thin geometries, such as batteries for credit cards and other such applications.

I can definitely see why lithium ion is in use more than LiPo, after having learned a lot about LiPo battery technology and high performance electric motors and things like that. With the cheap manufacturing process and corner cutting that goes on with such a scale of mass production like main stream smart phones, planes would be falling out of the sky due to all the smartphones that would be exploding.
I use to argue the other way, that as long as people used them responsibly and didn't jack around with voltage changes and used OEM chargers it wasn't dangerous. Then I started paying attention online to how many people will plug their phone up to any charger they find buried in the back of their family's chicken coup dumping grounds.
Lipo batteries are MORE dangerous and susceptible to overcharging than Li-Ion. Lipo batteries expand when at a high state of charge, and overcharging causes rapid degradation of the cell, to the point where it short circuits itself and explodes in flames. That's why those of us in the RC community use fire socks to contain charging Li-Pos...

My old droid X came with a LiPo batterry...after just 4 months of use it started to expand and get very hot...luckily i heard about this issue and bought a li-ion and the phone still works the last i knew...i gave it to a buddy like a month or two ago.
i think Rezound take more power then its tell in idle mode
for example if the phone idle for 10 hours and u got 50% left its will drain faster
then using it for 1 hour and then get 50%
also using the phone while recharging make the battery percent not correct
slow recharging can help battery recharge more energy

Those are wakelock issues that are easily fixable...have you looked into this and disabled them....alot of people have had alot less battery drain after doing so...i suggest viewing whats juicing down your phone to ensure that is what it is...a few of the 4.3 threads have explained the issue....LiPo batteries i hate to say it are made cheap and you get what you pay for...i'm speaking from pure experience
I used to have a SM-9005 In Pink on TMO, however my dog decided it would be a good thing to pee on (thus causing acidic corrosion). The phone had the 10K MAH Battery from Zerolemon,
The N9005 itself worked, and did not...its mainboard became corroded where the display connector is and went all matrixy. The battery has 1 corroded strip, one is half corroded, and the rest are fine. I inserted it into the 900P, and it works fine. However battery drain seems to be much...faster...and phone turned off three times by itself. When I turned it on however the battery % went...UP!
Is there an app that will allow me to see how much MAH is still working in the battery? I would imagine there are dead portions & I am pretty sure NFC is not usable anymore.
After flashing a rom away from stock turning off seems to not be an issue and all I know is its been running 3943mv...

I have the feeling that you're playing with fire here.
Using a corroded battery is never a good idea. You have already said that the contacts are corroded and you've seen degraded battery performance and, quite frankly, erratic behavior from the battery.
Continuing to use this battery because it still technically "works" would be, in my opinion, irresponsible. Best-case the battery continues to degrade over time (as all batteries do). Worst-case would be a fried phone and/or property damage.
In my opinion, risking the life of a $600 smartphone isn't worth it for a battery that you can buy for $15 on Amazon.

Yeah,
It just started to randomly turn phone off even on normal rom so I switched it back out for stock battery.
After looking at several posts in XDA and Reddit, it seems that the BLOD or BootLoop of Death is happening to devices everyday as we approach the 2 year mark of the N6P release. Seems like a hardware issue or maybe a combination of both. My question is that do you guys think that this issue is actually a large number of lemons or that there is really a design flaw. Will all 6Ps eventually BLOD? Is it a matter of If or When?
Also it seems that the batteries were indeed pretty bad, with 4 users that I know personally all experiencing the degradation.
Well, it's not all 6P's. I bought my 6P last January 18 months + and I still get 6.5 to 7 hours of screen on time. Using Accubattery my estimated capacity is still 88% 3,028mah. I can run my phone to 10% no reboots or shut downs. It's really in how you take care of your battery.
And before you ask, no I haven't changed my battery out. I've never opened my phone due to the fact I want to sell it soon and afraid they heat gun would warp things on the phone.

Curious if you've seen or heard anything that'd validate your fear... it's certainly reasonable to be cautious, and it does NOT look like an easy process by any means but why the heat gun? It's a very common tool to use for jobs like this.
But to be clear, I too worry the phone won't look/feel the same after a successful battery replacement.
Of course skill levels vary greatly.

I've seen or heard nothing, but since I'm upgrading to OP5 I was going to sell my 6P to help cover some costs. Looks like they are still selling for about 300-350. That's a nice chunk off the 540 of the OP5. My phone shows zero signs of wear and have never once dropped a phone. It looks like it came out of the box last night and plan to keep it that way for sale.

Gotcha. And thats a hell of a deal! I've been thinking of upgrading, OP5 is really tempting. If I got $350 for my 6p itd be like a 45% discount. Much better than the trade-ins carriers give you.
Edit-No it's like a 70% discount! $539 for 128 gb 8gb ram. For some reason I thought the base model came in at around $700

Really glad to see that you've preserved your battery well. I had to repair/replace my mobo and battery under warranty but I'm worried that the issues will happen again eventually due to poor manufacturing.
I just saw this over at the google tracker and wanted to share it.
https://issuetracker.google.com/issues/37130791#comment598
[email protected] <[email protected]> #597 Jun 24, 2017 07:53AM
For those of you hit with this problem and who have been denied warranty or are having no joy with either Google or Huawei, I have found a solution, albeit not the best of solutions but one that will have at least have a 60% chance of bringing back to life your Nexus 6P.
So after running some solid tests over the last week and abit on a few Nexus devices hit with the BLOD, I have found the following:
* BLOD Issue is not a software related Issue, Well not in full only in part, 6.0.1 handles and reacts to the sudden voltage drop that happens with the shockingly bad battery in our phones, it reacts to the loss differently so something changed in the newer versions 7.X.X that must trigger the battery to do something different and then causes the phone to BLOD, though the 6.X.X train was not entirely immune from it, the phone would hold up longer.
* Through various tests both with electronic hardware and software on the phone, you can physically watch the battery health drop sharply on a daily basis, these batteries are really that bad.
* The OEM Battery is a POS, when it gets put under load the Voltage tanks and tanks sharply, when it is not under heavy load and running at <31deg/cel the phone will work but only if the following conditions are meet... (1) The motherboard has not been fried by the battery shorting it out, a small IC chip appears to get damanged by it from what we can tell when we did testing on about 4 phones, but not on every phone or (2) the battery health is well enough to keep powering the phone.
* Here is where the problem gets interesting, the more the battery gets put under load, the more it degrades and rapidly, my current Nexus 6P 128GB Frost White version which is getting replaced on Monday by Google is down to 36% battery health, meaning if it drops below 60% battery life the phone just shuts down, so to prevent it from going into bootloop I have to keep it above 60% and each day the battery health is dropping even more roughly a 1% very two to three days at the moment.
* So we decided to put in a Generic battery into one of the 64GB versions that is stuck on BLOD, and it was nothing more than a battery from HK some cheap no-name of eBay, and BOOM! The phone boots up and comes to life again...
* However I have noticed a pattern on three devices I tested this on over the last week, I think the original battery at some point ends up damaging the PCB (Motherboard) and from what we could observer this would be the norm, if your battery is spiking and doing all sorts of things it shouldn't be, it has the potential to fry other components. There isthree of us doing these tests with one being an electronics engineer and the other two of us just being tech heads who repairs phones as a hobby.
* Now if we put back in the OEM battery, guess what? The phone would not boot up, it would just BLOD and on the meters the battery would just spray out wild voltage and all over the joint, these are really crap and awefully bad batteries that Huawei have put in the Nexus 6P, In fact we are not sure why they dont blow up like the Note 7 phones did, given how erradic the voltage spikes are.
* I can safely say that the Huawei made Nexus 6P has a huge problem with the installed battery, which by extension is also causing electronics to fail if it gets caught in the BLOD for too long and overheats the phone. My advise, if your phone goes into BLOD then don't strain, stop using it stright away, dont stree the phone too much, get the battery replaced ASAP, find someone who knows how to open it and replae the battery inside of it with a $7-$16 battery that you can get of eBay, this will at least bring your phone back to life.
I have spent about $400 on testing this to get to the bottom of it, having to buy batteries, run multiple tests, and also buy broken Nexus 6P Phones, at least I can get some of it back by selling the phones that have been brought back to life I guess.
Good Luck peeps, and my advice is to stay away from any Huawei Phones, because if has happened to this phone which was supposed to be a flagship, then it can happen to other Huawei phones if they are using the same or similar batteries, unless they knew all along and have changed them.... Which now makes me wnt to buy other broken Huawei phones and see if they have changed them.
Cheers,
David.

Yeah, fortunately I haven't had any issues with hardware on my phone. I'm curious if we'd ever see numbers hardware failure rate.
I've loved my 6P. I'm gonna miss the front facing speakers and QHD display. I may not notice the difference in 1440p to 1080p done I don't need with VR.
I share the same experience as Eric214, I have the phone since November 2015, my Accubattery show 93% 3191, I have all update installed thru OTA. Never rooted or installed custom ROM, here is my stat from Accubattery
Sent from my Nexus 6P using XDA-Developers Legacy app

I have literally never gotten that much sot on this phone, I feel like even if I didn't install any apps and left it in airplane mode I still wouldn't.
My new s7 edge gets me crazy battery life, but the 6p has been disappointing as far as battery life goes.
I think the bootloops and battery dissipation are caused by overheating of the 810, though that's just my professional opinion. Components don't like heat, especially when packed so closely together.
I had this battery issue after 14 months, replaced it 10 days ago - AccuBattery said my battery had something about 40%, now it says 101%. Everything back to normal.
Funny thing is: a month ago, AccuBattery showed 88% as well, everything working fine. Suddenly, 52% and the shutdowns began (no BLOD). I lived with this scenario for 15 days (battery health going down fast), almost bought an iPhone to replace it. Digging around I found a post from a Brazilian dude that brought its N6P back to life buying a battery from a given seller in a known online platform here and I decided to give it a try - battery and replacement costed 12% of what I paid on my phone. I expect to have it working until Pixel 2 pops up.
I'm in the group that after just 14 months my battery is at 67% of it original capacity and my SOT is around 2 hours. The worse battery performance of any phone I've ever owned. And I take care of my battery rarely will I let it drop below 60%, as I try to avoid deep discharges that harm battery longevity.
But no boot looping thus far.
as for the long post mentioning updates from MM to Nougat, i believe that the only thing i defintely did notice was with the battery behavior, the first weeks it took much longer to fully charge the battery , and it freaked me out.
now it is kind of normal again, i rooted my 6p the day i have got it haha.
i love flashing custom roms/kernels.
had the 6p for about 10 months now, i love it and really hope that it won't let me down quick.
at least another year would be nice, or 2.
So according to what @cyberedward mentioned from Google tracker replacing EOL battery with new Huawei made battery is like setting timer in a time bomb to another value ...
I don't know if they'll all bootloop but the battery is crap. After my experience that I documented in another thread, Id doubt anyone who's used the phone for a year has a battery thats holding anywhere close to full capacity.
Mine also shuts down at 20%. Now 4 days out of warranty. I'm gonna fight with the people at Huawei to get it replaced but best case scenario, I have to find a temporary phone for however long it takes to get it fixed.
3 year old phone?-I guess cut your loses.
But within a year?... complete BS! It's defective and they should recall them all.
***And to the OPs original question--what sucks is theres no known cause for the bootloop so you could get the battery fixed and within days, weeks, months you might also deal with that.

Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

Wow I did not know any of this. I will be following this thanks for sharing.
how long is the battery lasting if you are only going down to 50 and up to 90?
Gees! Below 50% really. I would tend to agree somewhat. I never let my phone fall below 20% and usually charge until 97% more or less. But 90-50. I don't want to be walking around with a battery back. I need my phone to last all day and 40% of the battery just won't cut it.
Xuck that !! I have a 3000mah battery for a reason if it goes then it goes ill most likely have another phone by then.Not gonna sit here to nickel and dime my usage that's not why I got this phone .
GM makes the Li batteries last in the volt and bolt 10 years by not letting the car drain the batteries more than 2/3rds down, leaving the batteries at 1/3rd charge. Tesla does it too.

Nah, I don't own my phones for more than a year so this doesn't apply to me. I'd rather keep using it from 100-1 just like I've been doing for years. I wouldn't be able to stand only getting an hour of use and charging it 3 times a day.
This battery information applies to all devices that use this type of battery be they Samsung or other brands. Its not just the Note 8. It applies equally to your Oral-B tooth brush! :laugh:

this is a good habit to charge often at 50%. i usually let the battery run down to like 20% or less then charge. then when i have to go somewhere and i cant play with my phone anymore cus i worry i going to run down the battery.
Question are the "300-2500" charge cycles just as it says? I mean if I put it on the charger in the car for a 10 minute drive is that a cycle along with an overnight charge? If it is we should really only be putting it on the charger from the 50-90% with a guaranteed fast charge time of at least 30+mins to get the maximum charge cycles for the lifespan?

This was a really well written down to earth article about battery care. Thank you. I still have friends, family, and coworkers that insist on running their batteries to 0%. I can't convince them otherwise. Although my batteries degrade, it's never been anything easy shattering. Just notice an hour or two shaved of over a couple years life. As the article states, there is no way around this and I won't be a slave to my battery. In that note, I top off when I can.
My battery on my old phone tended to get to around the 40% at the end fo the work day, then I'd plug it in usually around the 20-30% and it still lasted 2+ years 'til I got a new battery. Now it's about 50% at the end of the day. But with Fast Charge, what do they expect people to do, plug it in for an hour, then unplug it, then go to sleep, wake up with 60% battery, go to work and then charge it for an hour when you get there?
The lie of requiring a non replaceable battery for water proofing is also an issue. Forced obsolescence sucks....

Too black and white.
It is possible to offer some water resistance to a mobile that has a removable battery, S5 for eg.
In general such water resistance is small and is often abused by the owner causing problems. Hardly any owner reads the instruction manual that outlines what ones device can and cannot do, what the IP rating means in REAL terms etc
"Forced obsolescence" mmmmm, a battery can be changed in the Note 8. I understand your point though.
Ryland
this has been around for years. Doesn't make it very convenient to use nothing below 50%! I'd need at least an 8000 mh battery!! Therefore Samsung IS using too small a batteries in its top of the range device!

Totaly agree......
We then have to ask 'ourselves' WHY! Who forced Mobile brands to make anorexic devices? WE DID. We wanted thin small large wide slim ...........we got it and now pay the price.
I personally don't care if the device is thicker with a larger battery, for me its not a problem. For so many size was a major issue so the manufacture's listened and came up with these ultra thin mobiles that are vulnerable to dropping and breaking etc. off topic.
I find it totally bizarre that we spend mega bucks on such devices only to find we are educated to use them on software that reduces said mobile to the performance of a phone costing 100€! I may add many posters where disappointed when the Note 8 didn't have a 4k screen! Can you imagine the battery issues then?
Now we read this Samsung article and find we would need to charge our mobile several times a day as well as run it on a vastly reduced software programme. In reality that article is saying the battery is only operating efficiently at 40% of its total capacity before we start to degrade its life! Its all so absurd. What are we doing here folks?
Only one answer to this, either drop the performance OR vastly improve battery technology and fast.

I'm not sure how usefull this is for the new samsung phones though, as the release of the S8 Samsung improved the battery.
Samsung Mobile R&D VP Bookeun Oh told me, "I focused on maintaining the durability of the battery over the long term, over hundreds of charging cycles. For example, after approximately six months of normal usage, the battery in the S8 will outperform previous batteries. While most batteries hold about 80 percent of their charge after two years in usual cases, this battery should be capable of 95 percent of its original capacity."

PC mag S8 review
I am sorry but i will use my phone all day and charge overnight. If you can't use past 50% what is the point???? My pixel xl i have had since day 1 and use all day everyday and charge overnight and noticed no real decrease in battery life except a little change with oreo!
Outdated info and not necessary.
0% on your device is still considerably above what is considered the bottom line cell voltage before excessive discharge detrimental affects capacity.
A lot of engineering has gone into these devices to squeeze every possible mAh out of the packs, have a decent life expectancy AND operate safely. There is no need to strive for certain numbers and forcibly change your usage habits. There may or may not be a demonstrably better result long term but honestly is it worth worrying about?
And for removable packs...
Forget it. That's a thing of the past.
If devices had battery life like the Skyrocket, sure I see the NEED for a swappable pack.
But not now.
Having a sealed device makes it feel solid and keeps intrusion protection intact.
Holding an older device in hand, it seems almost laughable today. It creaks and groans and feels super cheap in comparison like some dollar store toy!
