hi I've heard plenty of times that you should charge your phone once you get it or charge overnight..is this true in anyway? I always go straight to playing with my new phone and then charge once battery dies..any thoughts on this myth?
Hi. I have heard a few different things about this. I think there is a thread on here I read about it as well.
First is that it won't matter because batteries no longer need to have that memory thing.
Then there was one that said let it deplete, charge it and then when the light goes green unplug it and replug it in. The light will go red for a few more minutes and then green. That will set the battery.
Then I also read that you shouldn't charge it completely or let it completely deplete because that will lessen the charge over time
The last I heard is that (and this was under the discussion about extended batteries if I remember correctly) the batteries are made so that the battery meter tells us it is dead even though there is still a little bit of a charge on the battery that way it doesn't do anything bad to it.
So I really think it depends on who you listen to. I did the let it deplete and charge it thing once so far. I get decent battery life. I tested it and got 10 hours out of it with medium usage and I usually get more when I toggle off the 4g when not using it but haven't timed how long for that yet.
Hope that helps until someone who knows more specifics posts something.

I don't think it matters any more. I plugged mine in after I did initial setup and let it charge to green light, didn't do any special bump charging or charging while off. The battery is designed to be used as is, without any tricks. Always overcharging to 100% or completely draining to 0% is probably worse than just using it normally and plugging it in when you notice it's relatively low.
There's a battery log that Android keeps regarding voltage and reported capacity that it uses to adjust the percentage display that you see on your phone. This changes over time as it gets a better idea of how the battery discharges, so built into your phone is a mechanism to make sure the reported capacity is accurate. If it gets "off" a bit, like if you see a huge spike up or down in battery capacity after a reboot, it's just adjusting itself.
But, as you know, Android users love to control everything by themselves, and not leave anything to some process behind the scenes. Hence the clamor for root so we can install whatever we want. So some people like to trick this adjustment mechanism by force charging the phone to full when it's off, which gives the battery capacity adjustment mechanism a "true" full charge to base its reporting on. Also, I don't believe the kernels in stock ROMs will charge to what it believes a full 100% charge is, to protect the battery life. Bump charging kind of gets around that, if I understand the process correctly.
Also, I don't charge overnight (lack of outlets in bedroom) so I make sure it's topped off before I go to bed. Even if it's not, it can make it through the night just fine, since it's not being used. So that's not that much of an issue anyway.
TL; DR: Just use it, plug it in when you need to.
Hi this is my first ever post so please bear with me, my lumia like many others suffers from ridiculous battery drain I have the new software and yes I can now charge to the max. However the battery cannot last the day out until I discovered this. Most people I know continually top up there battery, but if you just let it completely die then do a full charge overnight you may like me notice a massive increase in battery life, I have changed nothing about the way I use my phone the only difference is it now lasts 2 days easily.
The figures quoted in battery saver have not changed but as the day goes on the time since last charge goes up but so does the estimated battery life.
My phone is now IMO fantastic.
Maybe if you tried this it might work for you too, do hope so.
One word of caution when the phone has died the phone cannot be switched on until charger has been plugged in for some time, in my case about 20 minutes after plug in the phone switches itself on.
Please try and maybe you will also have the most amazing phone too.

I think I experienced something similar. I then flashed the new firmware and am back to lower battery life. Need to take the time for a few discharge cycles.
The problem with this approach is that some Lumia 800's cannot turn on after a full discharge. People have gone to great lengths to be able to get a tiny bit of charge so that it could power on. Some people have had to send them back for repair.
Question to TS. Do you let it completely die every time now or can you charge it whenever and still get the great battery life?
battery fix maybe
Hi after letting the phone die I have not done it again since, I just top up as needed or at night just as you would normally do.
Hope this helps.
Okey. When you say "completely let it die" do you mean letting it drain and turn off. Or do you start it once again after the first turning off and let it die again?
battery fix maybey
Just use the phone till it turns itself off, then plug in charger, this is when you may have to wait for the phone to switch on, mine turns itself on after about 20 minutes, charge as normal then use as normal, charging as you would normally do.
Good luck.
I did this once intentionally about two weeks ago. Did not notice any difference really. I do not have "bad" battery life to begin with. Not great either though. But it easily lasts a full day with heavy usage which is all I need really.
12 hours since last charge. 73% left on battery. I have used it "normally". About 10 quick calls. A few messages. Browsing on the marketplace installing a few apps editing contacts etc...
I'm pretty heavy on my usage, too. Lots of Mix Radio, sometimes played via bluetooth.
My wifes x2 display is using 59% battery. Weve changed the timeout to 30s and brightness down really low. But her. Battery still dies very fast. Its only 2 months old. We ha e disabled bt wifi and gps. Any other tips?
One other question. When her phone dies she cannot plug it in and turn it on or it gets stuck on the motorola logo. Qe have to wait till droid boot animation to plug it in. Any ideas?

If you plug it in from off do you see the charging screen? Try plugging it in and holding the power button simultaneously if the phone is off.
Is the phone rooted and romd or stock?
Is it running 2.3.4?
Sent from my DROID X2 using xda premium
Its running 2.3.4 rooted but not romd. I had the phone for about a month and had no issues with it. However i never allowed it to die. Shes not a heavy user but my main concern is why the display uses 59% where my d4 uses only 26% on the same settings as hers. Can i unroot the phone in case i have to return it under warranty?
Sent from my DROID4 using xda premium
when the phone dies you need to plug it in and wait until the battery on charge only screen shows at least 10% before the system will, allow you to turn it on
if you have BSR installed tho, as soon as it dies you can plug it in and when BSR comes up you can just choose reboot system now.
and the reason you d4 uses less battery on screen it's because I believe it is an amoled screen, which consumes much, lower power levels than an LCD screen

Have you tried recalibrating the battery too?
No. How do i do that? Thanks
Sent from my DROID4 using xda premium
First, make sure the battery is completely charged, then boot into custom recovery (BSR). Go to advanced options (towards the bottom of the list) and there should be an option that says 'recalibrate battery'. Once you recalibrate it, reboot back into android. I usually always let my battery run completely out after doing a recalibration before recharging it after a re-cal. If you find on your first discharge after recalibrating that your phone tells you you've only got 20% left and it would normally only last an hour before, depending if it needed the re-cal it may last 2 hours. Those numbers are just hypotheticals. Point is, recalibrating lets android know it's for sure 100% full at the start, but it doesn't necesarily know the end point until it gets there by allowing a full discharge. Also, the lithium batteries our phones use do best when recharged around 15-20%. It's actually bad to let them completely discharge all the time. And if you have multiple batteries and one may be sitting for a while, it's best to store them between 30-40%. Let me know if you need any more clarification.
Im going to try that thank you

More importantly, if you are already rooted and such, why not run a custom ROM? CM7 and/or Eclipse should give you a good boost in battery life. Running CM7 my standard battery lasts 18-24 hours with light ish usage. And that's with my original battery from when the DX2 first came out. I also have an extended battery I am running right now, but don't have data on that one yet since it's still discharging now. I do know that swapping between batteries of different capacities pisses android off sometimes though lol. Aside from custom roms, there are scripts and apps/software-based mods that can help it significantly too. Namely, wifi vs 3g usage, turning 3g data off when your phone is not being used, etc... I started off with an original DX but VZW gave me a free upgrade to DX2 after my 6th warrantied DX. I miss Rubix's ROM and being able to overclock and undervolt... My DX would last 2+ days sometimes when I had it all dialed in.
Its now my wifes phone. Since she already has had time getting used to stock i doubt she'll let me put a rom on it lol. But ill try

Well fortunately you've got a Blur-based and AOSP-based option for it. I know what you mean though, my gf likes her Sense-based UI, but had to give it up for a semi-funtioning Eris. I think she is getting a Bionic sooner than later... HTC is garbage.

Or you can download the app battery calibrator (haar a red Android as the pic) and follow the directions

letting your battery die completely is not recommended no matter what you've been Told
Li-on batteries were designed to last longer when you don't let it die completely
start charging around 15%-10%, 5 is pushing it cuz its most likely gonna shut down before you see 5, trust me, it's bad for the life of tour battery to let it drain completely, just Google Li-on battery life, recommendations and u can read for yourself lol

Yeah I know you're not *supposed* to let them discharge all the way but sometimes you have to and sometimes it just happens. For instance, my extended battery that I just did a re-cal on the other day has been sitting at 1% for the past few hours and is currently reading 1day 12 hours of uptime. (I shut it off the other night though and it is still discharging from its initial charge that I did the re-cal on.) So if I would have recharged it at 5% or whatever, I would be losing a decent chunk of available battery because android thought it was empty when it really wasn't, thus skewing the battery's voltage window.

that will only happen with extended batteries or one of those "Chinese", aftermarket batteries
regardless, battery life of Li-on batteries will decrease from letting it completely discharge, the more times you do it, the less your battery health will be.(BTW when do you "have to" let it discharge completely? , I'm not "calling you out or trying to "make you look stupid" or anything, I'm just curious what you meant by that?)
when I say 15-5% don't look at it as when Android reports that percentage, the x2 will, NEVER show an extended battery percentage correctly no matter how many times you "calibrate" that's just how it goes, it doesn't realize there is a higher capacity battery in the device larger than 1500mah, what you wanna do is use a battery voltage widget to monitor battery left, when it starts to get around 3500mV is when you are gonna want to charge I believe, (I think that 3200 is completely dead, and 4200 is topped off)
also,, wiping battery stats is a useless practice, not long ago I believe a Google developer wrote about why it's useless, apparently battery stats only has to do with the battery use settings stats about which apps have used which amount of battery. the battery stats gets reset/wiped EVERY time you get to a near fill-full charge (hence why the battery use graph resets itself when u almost fully charged, if you stop charging around 60-70% it wont reset)

Thanks for pointing that out. I regularly swap between my standard and extended batteries (both straight from VZW) because I'm always out and about and have used re-cal's to keep the perceived percentages from being skewed since I like to know how much life I have left in my phone so I know if I am gonna be able to find my way home or not, lol. (I ride my bike far and wide.)
I remember reading a while back that every time you un-plug your phone from a full charge that battery bin file gets re-written as 100%. So regardless of what android reports, yes, you will always get to use your battery until it is fully dead, but when swapping between two different capacities of batteries the reported percentages get skewed. And as I mentioned before, more often than not I am far from home on a bicycle in a city I only know a fraction of, and many nights somewhat inebriated, haha. I <3 my android, but it can certainly be a lot of work to keep up with.

trust me, I know exactly what you're talkin bout
except mostly riding buses/trains for mE
I have two standard and one extended, I always use the extend first since it will never report correctly when I'm out, then I switch to the standard ones so when they are running low, I KNOW when they will die lol
same here, wifes x2 battery last 2 days..awesome
I know for a fact that my battery level is incorrect. It's a 2500mAh battery, and yet after a couple minutes of heavy use, the battery level will drop to zero and the device will shut itself off.
Weirdly enough, I have this same issue with my MacBook, and I've figured out (at least on the MacBook) what the problem is: the machine isn't calculating the remaining time/percent correctly. If I don't use it to do power-instensive tasks, it will be fine up until the battery truly drains. But if I run, say, high-graphics video games, it will detect the battery's getting used very quickly, somewhere along the line it will freak out thinking that this battery drain is leaving it with seconds to spare, and will shut down. If I press the power button to start up, it won't, only displaying the 'out of battery' symbol on the screen. But, in actuality, there's usually about 30-50% battery left in there. How do I know? If I apply the charger for a bit, even for two seconds and then detaching, forcing the machine to recalculate the remaining battery, it will turn back on and have 30-50% left for me to use.
Here's the thing, though: with my phone, I usually don't have anywhere to charge it. So I'll unplug it in the morning to last me all day, hop on a bus to explore the city, forget about this issue and launch a graphics-intensive game, and then only realise what I've done four or five minutes later when it shuts down on me, thinking the battery's completely depleted.
So here's my question: How can I force the phone to ignore the battery level, and keep sucking juice from it whilst there's juice to be had? I know, I know, it shuts down for my own good, to make sure it has enough battery so that it can power back on again later. But right now, this usually-useful feature is rendering my phone virtually useless. Any advice?
Thanks.
After my stock battery started dying and not holding the charge anymore I bought two new aftermarket batteries (2300mAh) everything went fantastic for some time, then from one day to the other the battery I use daily started draining crazy (even 2% at time) I tried a lot of roms with no luck. Bad battery you say, here is the weird fact, the other battery which used maximum 4-5 times at month keeping it at half-charge, has the EXACT same drain that the other has. Is it possibile that something in the phone has gone nuts and is indicating wrong values? I also ran a full charge-discharge cycle preventing the low battery shutdown through xposed, and it shutdown some minutes after hitting 0%, at full charge indicates 4.300mV is it correct, isn't it?
Also using the *#0228# code (I can't recall now if it's correct) the charge level drops a lot like 30-50% and I noticed that the phone later stays at that % for quite a bit and also the heat from the battery draining stops and the phone stays very cool also while gaming, until it starts draining again
No one?
You can look at the simple battery-statistics in setting to find abnormal consumption by an app.
Otherwise buy a battery from Samsung's e-store: I bought several 'original' batteries (not for S3) from Amazon and mentioned too early wear after 1/2 year.
Replacement batteries are a waste of money. I had 2. 1 bloated and the other dies in a few minutes. Upgraded my phone instead.
I wish I stole my HTC M9.
