Battery

This is what I always do, when the battery reaches (lets say) 20%, but I still need to use the phone throughout the day, so I charge it till around 60 or 70% and then finish it before I sleep and charge again.
Will that affect the battery life or spoil it or something?

Well I have not noticed any sideeffects after similar usage as yours.
I will charge the Battery mostly at nights, no matter what is the current Battery level.
I am more worried about that I'm without phone because of empty Battery than I probably must buy new Battery earlier than "normally".

But I usually charge it in the evening because it will be really low till then and will not last me till night time. But I will charge it till around 60 70%. Just afraid that it will shorten my batt lifespan.

Trouble calibrating Desire battery.

Hi all. Having trouble calibrating my battery. I even went as far as to buying Battery Monitor Widget Pro. But to no avail. When I unplug at 100%, my bat drops about 15 in less than an hour. After that it seems to use up the battery normally. At 20% it goes to power savings mode, turning off some stuff like wifi, etc... But then, at around 18,it shuts down unexpectedly and when I power back on and get into the OS, it says I have 0% and powers back off.
The problem is I don't know how to properly calibrate the battery. Most softwares I have tried only seem to make matters worse. Could anyone please help me out? I'd really appreciate it.

Fully charge, fully discharge, wipe battery stats in recovery, fully charge in powered off mode.. A few cycles ought to be enough.

Will try. Thanks!

[Q] CM7 battery percentage

Hello. I'm using CM7 nightly 256. And I have a problem with battery percentage indication.
I put my phone to charge at night and in the morning it have 81% of battery (number is varying. someday it stops on 65% and someday at 79%). But if I reboot the phone it's on 99%. How can I fix it?

Same problem on Rem_Puzzle_Rom V2.43!Phone charges very very very.........very slow or stops at 80 or 85%.

Errrr, maybe it's the charger.

If I remember correctly someone mentioned a long time ago he had sent his back to HTC and they said it was a mobo fault which can't be fixed by flashing, it does seem to be affecting a lot more people nowadays tho.

Problem with battery.

Hello all,
Before some days I came back to GB from ICS and my "Android System" drains much battery. I installed mexdroid and I changed to elitemod to see if it is mexdroid's problem, but I got the same problem with elitemod. (After 4~ hours discharging with 2-3 calls and 15 minutes play game only, I got 60% battery.) Does anyone know what is going on? Thank you.

Well, you could order a new battery for next to nothing and see if that helps. If not, try flashing a new kernel. I had a battery drain issue on a gb rom before i went to ics. I have had amazing battery life with ics.

Remember that every time you flash a new ROM, you need to do a couple battery cycles in order for the battery meter to recalibrate. Charge the phone to 100% (leave it on the charger for a while to make sure its really full) then use normally until about 10 or 20% (don't drain to zero, as this is not good for Li ion batteries). Repeat a couple times. Your battery meter is not accurate until you do this.

Thank you I will try this and I will report back to tell you if the problem exists

I usually let the battery drain until its almost dead before charging right after flashing a rom.

Yes you should definitely charge to 100 and let it drain to dead. That will calibrate it. Then just charge it back up.

[Q] New battery problems

Hi guys
recently i bought new battery because my old one used to jump
from 70% to 100% and had really bad battery life.
i replaced the battery and calibrated it and i noticed that the 20% from 100% to 80% goes down realy fast
should i recaibrate the battery?
what should i do? thanks!

It depends on the rom u r using.
All roms except stock based roms have this problem.

Im using aosp by maclaw studios
the weird thing is that the 70% acts like it 100% and im having really good battery life
from 70%

Its a problem in sumsung charge system.
In custom roms when u full charge battery it is about 80 % charged.

I think you should charge it when the phone is turned off. I noticed that my phone tells me it is "Charged" when it is turned on. However the actual percentage in Go Power Master is 80%.

so it has nothing to do with the battery quality and the battery calibration?
the problem will not appear in the stock rom?

Thats if needed. To check if the battery is fully charged, try these step.
1. Charge the when it is running until it says "Charged".
2. Turn off the phone and keep the charger plugged in.
3. The battery image will appear. If it is not full, wait till it full. When it shows 100% then it is fully charged.
Note that powering up the phone takes some significant amount of battery. If the battery is still draining fast. Calibrate may be needed.

enchanced rom shows 100 percent but still shows charging. So I guess it fully charges

Well the battery level seems to be jumping unusually from time to time . What i do is i wipe the battery stats from cwm , i leave it over night to fully charge without doing anything to it , calibrate the battery with `battery calibration` from playstore , full discharge and full charge again . I do this after each rom that i flash and it seems to do good and seems to point the right amount. Anyway the charge lasts as i hope it lasts , from 1 day if i do stuff with it like some wifi , some messaging , many minutes of calls .... to about 3 days if i do only calls. Cheers
