hello guys. i think that my battery is draining way too fast than it shouldn't be, my phone is now 9 months old. when i charge my phone last night, i saw that the battery percentage is on 92%. i just opened a game, just to check something. when i closed the game, the battery is now 100%. i think the game that i opened does not even exceed to 5mins.
do you think that my battery is not working properly? cause when i watch movies, approximately, 25-30% only of the battery discharges, but now it discharges up to 45-50%.
by the way, im on a locked bootloader running the existenz black version.
is there any way on how can i prolong my battery life? i use greenify (donated version).
how to calibrate the battery?
thanks guys.

Hey guys, I have a weird issue. Regardless what ROM I am on, my battery percentage will randomly drop like 10%
Randomly, I will be using it, I'll be at 70%, then it will just drop to 60%, normal use. Been happening a lot more recently.
Is this a sign of a battery going bad? I've had this phone roughly a year (Stock battery).
Thanks!
What does your battery life look like? A battery's performance WILL degrade over time, but if your battery life is still good enough for you, I don't see any harm in continuing to use it.
You could get an app like Battery Monitor Widget. It will keep track of usage and calculate the health of the battery. You can also try wiping battery stats (the app can do that too), it could just be the phone mis-reading the battery...
I got a full stock N7 16GB 4.2 OTA which I'm not planning to root or flash (that's what my One X is for =P).
I noticed that quite often if I leave my N7 for a night with about 40% battery life, in the morning it will fully shut down with about 14% battery life remaining. Checking battery usage I see a sharp, almost vertical drop. Something's destroying battery when it gets about half way.
Anybody else had this issue?

Try and fully discharge and charge it a couple of times. The battery may be poorly calibrated. U can use a battery drainer if you are impatient. https://play.google.com/store/search?q=battery+drainer&c=apps

I don't know which update it was put in but it seems Google have added something that shuts down the N7 automatically at 20% to save the battery. I don't know if this is for every unit or not but it's been doing it for me and a few friends who have them too. I guess this is to save the battery as it can affect the recharging efficiency and the battery will die faster than normal if you allow it to drain further.
From your picture it looks like it's doing as it should, shutting down at about 20%, and then guestimating the battery stats, which fools the reading. However dropping from 40% to 20% overnight sounds like you have one or more rogue apps installed causing some serious drain, unless it's something you know/want to be running of course.
After charging my battery fully to 100%, I unplug it from the charger and without even turning the screen on, the battery drains to 92% within one hour. I check the battery stats and there are maybe only a couple wakes during this time.
Sometimes, the battery shows a certain percentage longer than others. Example, my phone will be on 65% longer than it would be on 60%.
Battery still gives me a solid 2 days usage with about 3+ hours screen on time. The service menu also says that the battery is good.
Is there a way to get the battery reading to show more accurately?
Thanks,
Hope I could Help You
For your battery problem, I guess you could try calibrating it. And also try to install "Greenify" along with "Clean Master or 360 Security" and try to close all running apps before turning off the screen. I also turn on Stamina Mode when the battery is at 100%, in an attempt to further save battery life. And the result has been kinda meh, but well, battery drains about 1% per hour. It lasts about a day and half with light usage. In my case, light usage being, browsing, youtube videos for about 2 hours, listening to music, social networking and taking some pictures

Hey,
im using greenify (my phone is rooted). Battery is quite good for me though. I get about 3 days with light usage. I start charging my phone again when the battery gets to anywhere between 10-20%.
I read that maybe its better not to let it get so low?
I have no wake locks either.
Umm.. IMO, 10-20% is okay. I usually charge the phone when the battery gets around 5%. I read somewhere that charging battery too early can affect the battery's overall standby time (reducing it). It's better not to let the battery reach 0% though.
I had that happen with my Samsung Galaxy Note 2 earlier. I once let the battery dip all the way to 0% many times. After a few charge cycles, I found out that the battery was dead and wouldn't charge at all so I ended up buying a new battery :-/
Umm.. Coming back to our Z1's, could you try putting the phone in stamina mode everytime the phone is kept on standby mode? This boosted my battery life a lot I even put my phone on stamina mode throughout the whole night yesterday to test the battery life again, and when I switched on in the morning, I saw that the battery had dipped by just 2% (standby time of 7 hours). I'm really confused how your battery drops so fast, 100% to 92%.
Could you try calibrating the battery and then putting it in Stamina Mode while on Stanby and tell me the results? I hope I could help :fingers-crossed:

Yeah i could try to calibrate it. Im a little confused on what you do to calibrate the battery (ive read way to many opinions on this). Can you please tell me the steps.

I used this to help me - http://forum.xda-developers.com/showthread.php?t=1024867
I bought the phone yesterday. When I charged fully overnight and unplugged this morning around 7:30, it drained %10 of my juice and it's now 11:08. It means 2.85% drainage for 1 hour. I think that's a little huge drain and when I look in to what's draining, it shows up to be Android system. I don't know how you guys get that tremendius battery lives but it clearly seems, I can't get it now.
Oh when I look at the cpu usage, it seems it can go to deep sleep too.
Will it fix itself in a few days? What do you think?
Well bought this phone back in mid 2017,and because of sickness I haven't used it that much at all.
I charged the battery 11 times so far and was keeping the phone in a desk drawer.
A month ago I noticed that the phone won't turn on,so I plug the charger on and charged the battery to 100 %.
I supposed that the phone was on,I didn't turn it off,and the battery left to 0% and shutdown the phone.
I really can't say how long it was on 0% (suppose like maybe a month).
Today I noticed very bad battery results.
Batterylife with GSam Battery Monitor is around 12 h only.
Was the "bolded text" the reason that battery died or the reason was not using the phone for 2 years?
Is there a software to check the damage of the battery?
I installed accubattery pro but for some reason doesn't offer me Health status of battery.

I would give the battery a few full cycles to see it that sorts it or yes, the battery it would seem is on its last legs. I don't know what app to recommend as an alternative though. (My battery is 23 months old and still performs as it did when I brought the phone)
I would drain it to 5% (maybe 1%) then charge it to 100% (without using phone while charging) a few times.
Then see how it goes. Afterwards charge phone from 20% or 15%.
Ok.I will charge it to 100% and report you with results with duration time on battery and you tell me how bad is it
GSam Monitor:
Battery Life: 3d 19.9h (5h 26m active)
Screen On:3h 40m (1h 17m Max)
In Android: battery estimated battery life: 2d 1h
