Hi guys,
I charged battery till fully charged yesterday and I went to flash a firmware upgrade which took about 15 minutes in total and thereafter when my phone restarted, it showed me 39%, a huge 61% drop during this process and I checked the battery voltages in fastboot getvar all and using gsam battery app, it still showed me 4.2-4.3V which is usually a full charged battery. Now after charging a while, it suddenly goes back to 100%, any idea is this normal? This is the first time this is happening.
Hope to get some help and advice around here, thanks guys.
Screenshots after charging over an hour:
Just plugged into charger:

After charging over an hour, suddenly it shows up at 100%
You need to re-calibrate your battery. There are a few different ways I've read people doing it. I usually just let it totally drain, then charge it to full again without messing around with it. You may want to search for a proper method.

I use my phone everyday at medium use and the battery stays for one and half day but this time it is less than 30% with no use at all.
What should i do to fix this problem.please help.

did you by accident unplug it (after powering) with the screen off? Sometimes this causes the deep sleep issue. Before you unplug always put screen on and unlock.
Try a reset and let it refuel again
If that doesn't help, put device in flight mode, power off, take out battery for a few minutes, put it back, power on, untick flight mode.
There are more options to resolve this, do a search on 'deep sleep'
Hi guys, like the title says the last couple of days my battery has been really terrible. I'm currently running PAC 4.3 + yank's kernel. A few weeks ago when I installed both rom & kernel I had AMAZING battery life. Like, 24 hours+ and still 20-30% remaining.
Today I listened to music on the way to college for like 15 minutes (screen was off obv), checked my mail and other social networks in the morning when I woke up and again when I reached college. It was around 50% at that time which is crazy for me already. Then I leave my phone on my desk when I go for lunch and when I come back I have only like 23% remaining. While I took the below screenshots, it already down to 19 -.-
Just wondering whether anyone could help me understand these ss? The weird part is that I had really really good battery life a week ago but I didn't change anything much really. Thanks in advance!

Value changes, charge and check again.
Quick tip: If you're charging to 100 stop doing it. If you let your battery drop below 10% stop doing it. If you play on charge stop doing. It'll hit the battery life very slowly.
So i shouldnt charge beyond 100?
I normally charge overnight

Mine had 288.something
Then it deep discharged and now it has 310.something again.
I would not care too much about this value to be honest.
Stop charging overnight. It hurts the battery and reduces cycles. If you don't charge to 100 and leave it you'll get thrice the battery lifetime (should last 800+ cycles).
The values keep flitting, try charging the phone and see if value increases.
I've had this phone for about a week and this is the first instance where my phone has gone down to 10% battery in the matter in 8 hours with what I can only describe is light use. I get a few emails, most of the time it sits with the screen off. I checked the battery stats and saw Android OS at 21% usage followed by Cell Standby and Screen.
I am rooted at 5.0.1 but stock and encrypted. Only mods I have done is DPI at 493 and double tap to wake.
Anyone else experienced this before?
So I've been having that issue the past couple days too. I installed a program called BetterBatteryStats.
Yesterday I fired it up after having about half my battery drain in a matter of a few hours.
I saw that my deep sleep was about 3 hours, my awake was 8 or so hours but my screen on was only about 1 hour. Something was keeping my phone from sleeping.
I went threw and uninstalled everything I could think of that had either updated or been added since it started and now it seems to be sleeping again so I'd look at installed apps and updates.

Lately battery stats won't reset when I unplug my phone from the charger. It is midly annoying.but I wonder if it could be a sign of a more serious issue? Right now my time on battery is showing 44 hours and screen on 9 hours which is obviuosly not true.

Yes, obviously I tried that.LOL
Don't the stats only reset once the phone fully charges to 100% ?
I granted battery stat permissions to a few battery monitor apps and I thought the commands were not going through, but they battery stats did not update until the phone was charged above 90%. I guarantee if you charge your phone to at least 90% or preferably 100%, your stats will update as fragtion said.
I asked this question a few weeks ago to no avail.
To reset the battery stats dial *#9900# ( Snapdragon ) and then select the option Reset Battery stats.
