i made this post because people might be wondering about how to charge their phones.
(i say these things from experience so if different for anyone then let me know)
make it a habit not to charger until its at least 15% or less. i always charged my g1 and left it plugged in even at 100 and after weeks the battery life went to hell. i went through 3 batteries that way.
Also try not to use the phone while its charging. i cant really explain what the hell causes that but i know from experience of two other phones that the phone overheats and messes up the battery. so that means avoid over-night charging. i charge mine either before i go to sleep of first thing when i wake up.
also when ur charging ur phone, DO NOT put it under anything, like between a pillow the bed. ur phone will overheat like to the point of too hot to touch. also from experience.
Thanks man,that why my old battery started die'n so fast

I normally do this to calibrate battery:
1. Charge to 100 % with phone on
2. Unplug and turn off
3. Charge to 100% when off (i normally leave it for 10-15 minutes)
4. Then unplug, turn it on, then after fully booted turn it back off
5. put it back on charger till it fully charges again
6. boot into recovery and wipe battery stats
now use your phone as normally and give it 3-4 full charge cycles till the battery is properly calibrated.
Battery calibration is a app on the market. Check it out! It saves you from having to go into recovery and wiping battery stats

i follow all of this and i usually get around 20 hours of battery life. and ive only calibrated my battery once.

I'm curious I recalibrated my battery to last longer I usually lost around 7-10 percent over night. Now after calibration I only lost 3% and this is what my consumtion was and was curious is this normal or good. I'm getting 43% cell standby, 40 phone idle, 15% display and 2% OS. I was going to post a pic but is not letting me right now.

With my stock rom, I usually use about 3% over-night when the phone is shut-off.
So, either the stock batteries suck, or "off" doesn't really mean "off." I'm assuming the latter, since we have to pull the darn battery to get a true reset.
3% overnight sounds reasonable. Same here.

Maybe you have fast boot on. Or it sucks up a lot of juice just turning it on

Sure do (enabled by default). I'll switch it off tonight and see if the percentage changes in the morning.
so is fast boot something we want on or off?
I look at fast boot as hiberateing. Take that off and I believe your phone will actually shut down all the way. Fast boot is fast boot. After shutting it off and turning it back on and starts up quicker. Sounds like something that would suck a little bit of battery life over night.

With fastboot disabled and the phone shut off, you should see 0% to maybe 1% battery drain overnight.

Yeah I think its from powering down and back up that's it.

To recalibrate it I just powered up to 100% powerdown, unplug chord reboot into recovery go to advance and go to wipe battery bin. Reboot amd you should have a more accurate battery %. You should 4.2V at 100%
Sent from my Inspire 4G using XDA Premium App
3% is more than reasonable.
I lose like 1% per ~2 hours standby with active 3G data connection, and gmails pushing emails.
Last night I did something that may have been stupid. After my phone shut down on low battery, I restarted it twice following successive shutdowns. I did this to ensure the battery was completely drained because battery life has been noticeably shorter lately. After plugging into the charger, the phone did not begin charging and would not power on. I had to do a battery pull to get things working again. Is this a normal side effect of my ignorant action in draining the battery?
Unrooted, stock other than a few mainstream apps.
Sent from my HTC Inspire using XDA App
Yes this can be considered normal. There has to be enough battery for the phone to switch into charging mode and it appears you didn't have enough

Thanks. That makes sense.

I put a new rom on the phone and calibrated the battery via clockwork after the phone was charged to 100%. I took it off the charger after that and messed around with the phone for a while. The phone had 95% when I went to bed. When I woke up the phone was at 68%. What could cause this? The phone has never done this before until I calibrated the battery. Thanks you all so much

Just use the phone normally for a few days. It will calibrate itself.
OK thank you. Should I let it die then recharge??

I have read so many articles about how to re-calibrate android battery and most of them involves deleting the batterystats.bin and this requires root. What worked for me without deleting batterystats.bin is this: disable fastboot from settings>>power
use your phone until it turns itself off then turn it on again. It should say that battery is at 1%. Use it until it turns itself off again. If it is really at 1%, then it should turn itself off right away. Charge it until the light is green and continue charging it for another hour. After an hour, pull the plug, turn it on, and you are good to go.
Try what works for you best but this is what I did for mine.
Edit: The idea here is to let android know the minimal charge state of the battery.
Thanks you all I am rooted and use cm7. I will give that a try and let you know how it goes

Hmm, the Android Revolution-Thread says says something else.
I quote " After flashing Android Revolution HD my battery drains much faster. What can I do?
A: Please charge your battery to 100%, boot your device in ClockworkMod Recovery and go to Advanced ---> Wipe Battery Stats "
You can also use " Battery Calibration " from the Market

i did a few things before but this seems to be the most thorough method check this link out and go through the steps. its a good way to get your battery the way you want it and keep an eye on it
I heard that leaving the phone plugged in for a long time can affect the battery's performance. Is it bad for me to leave my phone plugged in for 24 hrs+?

keeping an li-ion battery fully charged all the time is not so good for it, not because it can become "overcharged" but because your not using the battery it may suffer from capacity loss, the ideal environment for the battery would be to let it discharge to about 50-20% then charge it again till full at least once in a while so that it is maintaining its cycles and capacity. :good:
OK thanks.

I always charge mine for a couple hours before I go to bed that way I don't leave it overcharging. Throw it in airplane mode and go to bed that way ur battery doesn't drain too much overnight.

Also is it bad for the battery if you reboot a lot?
Pretty sure the phone's charge circuit isn't going to do anything to damage the battery. Once it's charged, it may go to a tiny maintenance trickle charge, but you will be fine. Rebooting also will just drain your battery, not damage it, as it uses a lot of CPU and I/O to get Android fully up and running.

Not bad for the battery but I guess you'll have to charge it again sooner
Nice thread on Li-Ion batteries http://forum.xda-developers.com/showthread.php?t=669497
So on a daily basis I should run the battery down to about 20-40%, and then charge to 90-95%?

I run mine down to 5% and charge it to 100%
Sent from my HTC One S using xda premium
it cuts off when its fully charged so i wouldnt worry, also you dont have to cycle charge li ion battery's even if you only run it down to 60% and charge it, it wont do it any harm, infact they like to be charged willy nilly as its keeps the ions jumping about or something, haha
Hi all
I will be getting my nexus 5 tomorrow and was just curious if there are ant does and donts with regards to charging the battery. The reason i ask is i currently have a HTC sensation and after 18 months the battery had to be replaced as it was simply not holding its charge. My routine was to charge it overnight every night and use it during the day.
Does charging it through the night cause damage? im just a little bit more concerned as i will not be able to replace the battery with it being sealed.
Thanks for any tips
Chris
Hi,
Take a look here: http://forum.xda-developers.com/showthread.php?t=2511647...
I used to do the same thing with my HTC Incredible... I learned that it can damage the battery over time by not allowing it to hold a charge. Now, when I get home (depending on remaining %) I charge my phone, and unplug it during the night.
If for some reason the battery dramatically drains overnight, I'll charge it when I'm getting ready to leave in the AM.
That is just my method, but I have had great results with it for my usage.
Plug it in...

Thanks i read the link ...and i also think i probably wont charge mine overnight, im convinced that had a hand to play in my battery going
I have had this phone since it was announced. I plug it in every night when I go to bed and leave it plugged in till I wake up. My battery is fine. I have done the same with my note 2 also. Never had any problems

It's not hard to pop the back cover off and replace the battery when it goes bad. I just dont worry about it and charge whenever and take it off the charger whenever.
