Root Am I Missing Something?

[EricS96521]

Here's what I did..

I recharged the phone, turned it off, bump charged it, rebooted into recovery and wiped the battery stats. I then used it for about 2 minutes to force stop a few apps, then I loaded up the music player, put my headphones in, set it to play all, then I went to bed.

This is what I woke up to.

It remained at 97% for about another 5 minutes and it began dropping a percentage every 2-3 minutes after that until it stopped at 91%.

damn. what battery do you have? with 5 hours awake time i'm down muuuuuuch more than that!

 

[EricS96521]

Stock battery.

As a matter of fact, when I woke up, it said the battery was still at 100% until I had turned the display on for about 5 minutes. Then it began dropping by about a percent every 2-3 minutes until it hit 91% and it kind of hung there.

I have it recharging now and will turn it off to bump charge and wipe the battery stats again.

I'll see where it goes from there.

Edit: And the music player doesn't use much battery at all, as long as you are using headphones.

Charging the phone counts as awake time if you do it via pc I think?

How do you wipe battery stats? Step by step idiot-proof instructions, please lol

Not that I am aware of. Mine is always set as 'charge only'.

And to Kori, you have to be rooted and have clockworkmod recovery installed.

If you have that, boot into recovery, go to advanced, and it will have an option to wipe battery stats.

What you need to do is charge the phone all the way, turn it off and bump charge it a few times, boot into recovery, wipe stats, then reboot. Now run the battery until it is dead and now your phone will have an accurate calibration of your battery.

You have to be rooted

If you are, bump charge your battery to full, boot into recovery, select "advanced" then select "wipe battery stats"

WIping battery stats has done something to similar to me before. I don't really know what to make of it other than wiping the battery stats seems to make the battery meter drain at a more consistent rate rather than dropping quickly then plateau'ing etc...

Whoops. No, I'm not rooted. Shucks.

 

[EricS96521]

Whoa. Battery was fully charged with no apps running and background data disabled. Over the past 2 hours my phone has dropped to 70%..the most significant loss being in the past hour when it went from 86%-72% with me never turning the display on.

Is it possible to have messed up a connection when I disassembled the phone?

 

[EricS96521]

Definitely something wacky going on.

Battery was at 61%, I booted into recovery and installed a new kernel, turned the phone back on and it says fully charged with the battery voltage at 4157 mv

It also says my battery temp is 64.4 degrees. It has never been that cool, and from holding it, it is at least 80-90 degrees.

 

[EricS96521]

Running the phone full out for the past 20 minutes..flashlight, gps, pandora, youtube, internet, everything and it STILL says fully charged.

I'm worried about this

 

[Crashumbc]

it takes SEVERAL charge re-charge cycles to properly calibrate the battery meter.

Because you wiped the history your going to see wacky stats for a few days...

 

[LaCeS OuT]

I don't see the point of wiping battery stats AFTER bump charging. If you don't bump charge everyday, you should wipe stats without bumping for an accurate meter.

+1^

Excellent point.

Froyo has saved my battery and phone from getting replaced with 2 cups and a string..

 

[howarmat]

if you dont charge the battery all the way to the TRUE 100% then the phone will never know 100%. if you just charged the battery to say 91% then erased the states, the phone will now treat 91% as 100%. Which would be incorrect.

It is measuring it in degrees Celsius; 64.4C is 147.9F. Your battery should never be reaching that temperature.

 

[EricS96521]

No...It said 64.4 F and 18 C
