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.

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 %.
Hi, I was experiencing some Terrible battery drains , so I factory reset the phone in hopes of fixing the issue. Running the bare minimum apps, and I'm.still getting 1% drain every 3 minutes. Specially when I'm merely listening to music. on the 1 hour commute this morning I lost 15% battery.
I'm on stock rogers 1.94 firmware.
I ran carat for the past month before the reset and it couldn't identify the cause.
tried to unlock bootloader in order to flash a Rom, but got confused and gave up haha
can you guys help me out,
thanks
Are you listening to the music in the cloud (Pandora, spotify etc)? Better battery stats is a great way to see what's going on. Do you have facebook/twitter set to push all updates or auto refresh in the background?

Battery readings right after a factory reset are not representative as the battery meter is now not calibrated. Charge the phone to 100%, leave it on the charger for a while to ensure any topoff charge. Then drain the battery to 10-20%, repeat a couple times to calibrate the battery meter. Then see if you are still getting fast battery drain.

you're right, I will report back after a few charge cycles
Will it be possible the drain relates to kernel?

Its always possible. Folks on here like to swap kernels, in hope of increasing battery life (even aside from governers and underclocking) But I've personally never noticed a huge change in battery drain just from swapping kernels. I'd try a different radio first. But the OP is still stock, so they might be looking for less invasive solutions.
Could some Rogers bloatware be causing some of the drain? I don't know what they put in there. But AT&T bloatware has often been blamed for big background data use and therefore battery drain.
I have a problem with the battery.
I`m running cw11 m6.
The battery indicator in the status bar sometimes jumps back and forth.
I reset the battery stats via the app "battery calibration".
I have not plugged in the charging cable during this time.
Is the battery broken or a rom bug?
Lock on the picture:
It happens. The graph is an estimation only. It periodically checks the battery Voltage for an accurate reading and adjusts the graph accordingly.
Wiping battery stats won't help anything.
[Info] What are battery stats and is wiping them helpful?

That is a lot more extreme than I've ever seen. Full charge your phone over night and see what happens after.
You don't need any app to calibrate your battery. It self calibrates every time you full charge your phone. By using something like Current Widget you can check when the phone is actually fully charged since it's not when it first reaches 100%.
I am having drastic battery drains from few days. First mobile was used to give 5-6 hrs on full charge now it only gives around 3hrs. Please check the battery status below and give solution of you have any.
I have already disabled WiFi scanning from location and advanced.

Discharge your battery completely. Use your phone till it has 0% battery left. Then charge it all the way up to 100% and start using it. Observe the battery life now. Use it till there's only 1-5% battery left and then check the battery stats. Or post the screenshot here.

Yes. That's exactly what I meant. It'll sort of calibrate the battery. Do it once or twice. If the battery drain still exists, then it's probably some app or some settings you changed recently that are causing the excessive battery drain.

Disable Wi-Fi scanning in location. Then do a network reset. It will solve your WiFi battery drain problem.
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:
