Flashed device, battery resetted 100%

Hey i flashed my device with the battery at around 80%.
after the flash it was 100%...
so this means i just lost 20% of my capacity? how do i fix this?

I don't believe you have lost capacity. It's only your gauge that's slightly altered. If you recharge your device fully(and about an extra 30min) you should have the regular capacity

How could going from 80% to 100% equate to a lost ???
it's posible that you'd gained the extra charges while the flashing process was going on ( because it was plugged in ?? ) ... if it wasn't ... no idea why

If i understand the post correctly they are equating am 80% to 100% a loss for 2 reasons:
1. because he would have lost charge while flashing due to the massive battery drain.
2. because now he is stating that his 100% is really only 80%
but i would probably just leave it charge overnight and you should be fine, the gauge just sounds to be off, it shouldnt be a true loss (unless the battery is bad)

Is there any other way to sync the battery with the device? I been trying a full discharge then charge.
I am using a mugen extended 3000mah battery and at 15% 10% and 1% it will stay there for some time before it starts to go down or turn off completely if it is reaches less than 1%.

I don't think you've lost capacity.
I believe you just did a quick check before flashing (and it was already charging before you started right?), and the battery gauge wasn't updated. I had this a couple of times while recharging. I take a quick look and think "this is gonna take another half hour". Five minutes latter I check and the charge led is green again.
Sometimes the battery metter lags a bit, you have to check it again to be sure when charging.
At least it happens to me.

a few cycles of full charge and discharge should put the battery meter in check...

Alrighty. I have done three so far. It has gotten better then the first time I got it. But its not perfect.

is it safe to discharge it to 0% so that it will shutdown? or what?

Battery Calibration - Once and for all!

I have read every possible thread you can imagine on battery calibration and can never seem to do this correctly, is it a myth? No matter what I do, if I restart my phone, I end up going from 100% down to 85-86% EVERY SINGLE time.
This is after "bumping it". (letting it drain all the way to 0% and then fully charging again).
This is after using BATTERY CALIBRATION in the market which was told works well. (again, advises you charge to 100% then "calibrate" it via the APP).
This is after charging it to 100% and restarting it, recharging up to 100%, restarting and recharging (repeat, repeat, repeat), and then going into bootloader and wiping battery stats.
None of these have worked, does someone have a sure fire EXACT way to do this properly or is at ALL just hype? Help.

Your battery will never say 100% after a reboot. It sucks up a lot of juice on a power up and the battery doesn't charge during powering on. I usually drop about 10% on a reboot using the rezound battery. That is normal behavior. If you can charge to 100% with the phone on then you're fine.

Interesting because I've never lost 15-16% consistently although I guess it using some juice to cycle makes sense. Anyone else seen 10+ every restart? Thanks for the help man in either case.

Hmm, never seen this before. On my phone which is running skyraider uc to 768mhz and uv only loses 1percent on reboot or doesn't even lose charge at all. Not sure why your phone is doing that.

I am running G3D uc to 768mhz and on restart I may lose 1 - 5% at most depending on if i made any changes that take a longer restart. I bet you are overclocked? no need, under clock to 768mhz and your phone will run as smooth as 1.2mhz..maybe smoother while using less battery

Running liquid 3.2.1 on my T-Bolt with the Rezound battery and I only lose 1% battery at boot up. Never lost more...oh and I have never calibrated my battery. Also I get about 8-10 hours of moderate to heavy use too. All stock clocks btw

Just to double check - or reword... do it this way - if you aren't already.
Charge to 100%.
Wipe Batt stats
Drain to zero without recharging in any way (AKA let it drain until it shuts off on you).
Recharge until 100% (till it says 100%, not just "green."). And unplug.
And you're good! Try that and check back in.

Battery Calibration doesn't work

Ignore the % number, it means nothing. Use the battery monitor widget or another program that will show you the actual battery voltage. A fully charged battery will be somewhere around 4200 mV and a discharged battery between 3600 and 3200 mV. I've also noticed that the rezound battery throws things off as the mAh rating doesn't match up to either of the thunderbolt batteries. This is why the battery monitor widget shows the rezound battery as 2750 mAh instead of 1620.

What I recommend to my Evo peeps [which I have] is this:
-Charge battery to 100%
-Wipe battery stats in recovery
-Let the battery drain, so it manually powers off
-Charge to 100% again, and good to go

By this I mean Google Developers have came out recently and said battery calibration does not increase or have any effect on the state of battery life. All wiping the battery stats does is wipe the stats as to what has been using the battery, etc.
still handy for when you flash a new rom to wipe the stats, but it doesn't improve battery life at all.

Actually, the post from Dianne @ Google said nothing about calibration. She only talked about wiping or deleting the battery stats file.

You are correct, however all the battery calibration apps available only delete the battery stats file. So like I said it doesn't affect battery life.

This is what I thought I had done but will do again. The problem is even after its 100% and in between your 1st and 2nd step when I reboot into recovery, it's no longer at 100% and sometimes down to 85%ish. I will try again tho, thanks!

That pretty much says it. Wiping stats and calibrations are placebos.

Yeah I read that too. But when I flashed my first rom on the tb I got abysmal battery life. 25% in like 20 min. I recalibrated and it got so much better. If its a placebo its a good one.

all that says is the the deleting the batterybin file doesn't help. The battery is handled by each by software outside of android itself. So, following the battery calibration from the manufacturer of your phone still might help.

25% in 20 minutes means nothing. The % is an estimated number. Find an app that reads the battery voltage if you want a true reading on the battery's charge. Full is 4.2 volts, dead is between 3.0 - 3.6 volts. Battery life should only be measured in hours from full to dead. I've seen my phone stick on 100% for several hours before as well as sticking at 20% for several hours. Ignore the %. Anyone spending all day looking at a % to judge their battery life should go back to a battery indicator that doesn't show %.

[Q] Any way to clear batt/data usage?

I'm looking for a way to clear the Data Usage and Battery Usage stats - is there a way? Or maybe there is some app that would give me better tracking of these things?
Also, I'm noticing that under battery usage, my pad is using a TON of battery for WiFi - like 87% of all usage. Is this normal?
Thanks!

Yes, thats normal.

If you have CWM you can clear battery stats in recovery and for the wifi make sure that its policy is "when asleep" or "Never when plugged in"

try battery calibrator on the market
just charge to full, click calibrate and unplug. might have to repeat once. it works by deleting battery stats.

Battery Problem..

Hey I am facing severe battery drainage problem...
The phone is been charged very very slowly when its on and drains very very quickly...
it charges a little fast when switched off but its still slow as compared to normal android phone...
help...
I charged around 50% in off phone and after in on the phone and the battery almost 0% in just 15 min...

First check your battery whether it is swollen or not..
If not try to calibrate your battery.. Remeber calibrate doesnt increase battery life it will rectify your battery stats.. I think your battery stat is showing wrong info..
Let the battery drain off completely charge until 100 dont take out while it is charging.. Calibrate and restart you phone..

I think you are right that my battery stats are not proper... because I just restarted my phone and my. battery gone to 73% from 23%....!!
and my battery is not swollen...
But can u tell me the calibration steps?

Simply install battery calibration app from play store i think after search 1st app will b the one.. Install it.. Instructions are given in the app just after install open it..
The instructions are simple anyway..

Big Overnight Battery Drain

The first screenshot is my battery life and as you can see Doze was applied but it still drained 10% in 8 hours. In the second screenshot of Better Battery Stats, it shows I have a lot of the phone being awake while the screen is off.
How can I figure out what is causing it to be awake and fix it?
Please let me know if you need other sections of battery stats or anything. Thanks

same things , im on on 10.3. it was pretty good during fresh install like 2 % in 6-7 hr. now 10% overnight drain everything off

PlusBeat installed? Had the same issue. No drain with it under 9, high drain under 10. BBS did not show this app. Found it only after freezing one app after another.

I really can't understand how you guys end up with these drains. Since I rooted I've taken about 7 updates to 10.0.2 , never wiped my phone and never encounter that type of idle drain. Check my screenshot it shows 0% drain in 6hrs with only 10% deep sleep which makes no sense at all. What's crazy is im trying to perform a battery test to get to 10hrs SOT with regular use but my uptime won't be accounted for in the battery menu because it starts calculating after you lose one percent. Thus the discrepancy in the screenshots

Some app is preventing your device from going into deep sleep. Facebook was the culprit for me.

Do you have a custom kernel installed? Something changed in a recent update & there's a service that goes haywire if you have a custom kernel & keeps one CPU core at 100% constantly. I found it in system logs as "vendor.oneplus.hardware.brain". My idle drain was over 4%/hr till I figured it out. See this post for how to stop it:
