I have the HTC HD2 as well and can get it down to about 2 hours per percentage point of battery which lasts me forever in standby. However, on my new G2 with Cyanogen mod RC3,2 and 1 I can not get it lower then 39 MA and I have nothing on on the phone that would take battery like that. All sync is off, no GPS, No back up, no data, no bluetooth, no wifi.
I noticed in the battery settings that the Android System is taking nearly 70 percent of my battery and I can not get it lower no matter what settings.
I turn off auto brightness, sound is minimal, leds are off, haptic feed back is off, brightness is at 25 percent.
I can not figure this out and its a deal killer for this phone for me since I was getting 3 and sometimes 4 days with these settings on on my HD2.
Anyone can help ??
heh... just because its taking 70% of the battery doesn't mean its draining it. on a 100% scale, something has to take that 100% up, and it SHOULD be the Android System. Get it?

Trust me, I know what I'm talking about. It shouldnt be more than about 6 to 8 percent.
I was able to get two hours per percentage point on an operating system that ran from the sd card which takes more power then an OS on the Nand since it is continually reading to get information back and forth.
Anyhow, Something is wrong as I am getting about 6-7 minutes per percentage point on this G2. That is horrible. Not acceptable either.
And that is in Standby Mode with the screen off and all the settings above.
Drain your phone's battery until it shuts off. Then turn it on again.
Then charge the phone to 100% battery.
Boot into recovery and wipe battery stats.
You're all set.

If android system is taking up 8 percent, then what in your opinion should be taking up the other 92% of battery usage?

Are you on stock? You are not using quick boot are you? That is a known bug in that app.
I am on SRF 1.1.1 and when I switched over I did the battery calibration where you charge while on (always to 100%), unplug, charge while off, unplug, charge while on, unplug and then wipe battery stats. I then downloaded and ran the battery calibration tool, ran my battery out and charged to full. It's a monster now. I can really say I'm one of those people who wandered around for an hour randomly doing things and checking my phone as usual and where I would have normally been at 94%, which is fine life after an hour, it just turned to 99% at the 1 hour point. I will keep watching to see if performance is better at first and wanes or what.

Where did you get this battery calibration tool? The market?
I think his issue is the big percentage changes upon reboot which is a bug and not an actual percentage drop. It was especially noted with Quick Boot.

Sure, but if he stops using reboot and calibrates his battery settings, won't that fix things?

Don't count a reboot and a major change in percentage as horrible battery life. I have been getting that recently because I beta test and when it drops like 40% on a reboot I power down, plug it into a charger, it goes back to where it should be, then I power back on and it is back at the level before the reboot. It is a bug somewhere. As for your normal usage, how many hours do you get on a full charge without any reboots? Users report anywhere from 10 hours to 18 hours with some usage (of course there are a few extraordinary cases out there).

Are you streaming music or playing mp3s stored on the phone? If you are streaming and the 3G or 4G keeps dropping out it will kill your battery constantly reconnecting.
I've never seen anything like this. My battery literally dropped 6 percent in a split second while I was looking at the %. Is this a manufacturer defect, would a factory reset do anything to help? Please Help.

No, not necessarily. It takes time for a system to properly calibrate the battery. You should always give it a few full charge cycles before assuming you have a problem.

This.
I wouldn't worry about it it likely hasn't calibrated yet, I've seen many of my devices do this, especially new or freshly wiped

You are overreacting. Large amount of power consumption in short time isn't unheard of. For example, it has been reported that phone searching for connections and syncing everything at once can cause large drops in battery meter. And battery meter isn't always accurate anyway.
If the battery drops more drastically and happens more than a couple of times, then I would worry.
My tablet does the same too it either goes from 78 to 76 or just skips from 30 to 26 randomly
The first day I got it, the battery went from ~50 to ~60. You read that right...it went up without charging. Just let the battery settle and it will become perfectly normal again.
Mine does the same, drop from 33% to 23% instantly. and while charging, it jumps from 94% to 100% too. But i do get 9:30 hrs use time with Chrome.
Still in the return period window, not sure to return it or not.
I think that the battery percentage sometimes freezes and doesnt update right. So once the software finally gets a good reading or update it will suddenly change alot. I had it stay at 85% for like 3 hours and was thinging, AWESOME this is amazing, then 15 minutes later it was at 50% and i was like, oh, damn it was just playing mind games with me.
The battery gauge doesn't really 'know' the charge state of the battery, it's just guessing more or less accurately based on a model of the battery.
It takes things like battery voltage, load, temperature, voltage change with varying load (to estimate internal resistance of the battery) to basically make an 'educated' guess of the charge state. There can be pretty big corrections of that guess - a 10% jump is very normal. It doesn't mean the battery charge state has changed, it just means the battery gauge has corrected it's estimate.
during charging, i seen that it increased 1% per every 4~6 mins from 1% to 94%, then it jumped to 100% from 94% in the next 6 mins.
It also skipped percentage 4~6 times while charging from 1% to 94%, 1% per skip.
I used Batterybot pro to monitor the battery, it will logs when the percentage has changed, that's how i know it was doing this.
I've been experiencing huge battery drops (from 10% up to 20%) after I reboot my phone. Is this a KitKat issue or is it my battery?
In the morning from 99% (after checking a few messages in the morning), I rebooted and I dropped 11% to 88%.
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one. :good:
I didnt found it on reboots, but i have this problem when i enter recovery. 20 minutes in recovery - i dont hace 20% of battery.

Hmmm that's strange.
I've noticed it usually drops more when I leave my headphones in.
full loaded ACE 2.
reboot cost u 5%
first 10 % gone in a few minutes for heavy users and in a few hours when deepsleep !!
what i wanna say.
the first 10 % gone in a few.
after that normal drain.
I often get this, although not as bad. I usually lose 2-5% on a reboot, sometimes up to 10%. The other week I charged it to 100% when it was off, turned it on and had 92%.
so is this actually a problem or is it normal for everyone?. Mine looses 5-8% in the first couple of minutes after I unplug the charger..
It's normal.

Its normal. I usually lose the first 5% of a full charge in a couple of minutes. After it gets to 95%, battery charge will drain normally depending on usage.

ok then, thanks...I just thought that this didn;t happen when I was on GB, but it doesn;t matter anyway..
If I reboot once, I will lose between 5 - 10% battery. However, if I reboot straight after the first reboot, I will lose between 0 - 2% battery. I've never really understood this.

Battery Charging Issue
Is this normal?
When I charge my battery whether it be from mains or USB computer it charges ok, but as soon as it gets to 100% it still says charging for a little time and doesn't report the unplug charger message right away.
With the Jellybean 4.1.2 system I don't get the alert tone when the battery reaches FULL, therefore I have a feeling that when it still says charging even though it's showing 100% that it's actually decreasing power at that point, any help please?
I have tried other batteries, and one in particular goes from 90% right up to 100% and seems to miss that last 10 percent, so I don't use that one now.
I have the most current firmware installed.
Buy a new one

when it says 100%, you still have to wait for a few minutes before it displays the green "full" icon in the upper left corner and asks you to disconnect the charger.
However, the first 5-8% always drains REALLY fast and not proportionally to the rest of the battery drain...
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one.

what about the initial drain? does the first 10% still drop fast or has this changed too with the new battery?
I just wish that JellyBean 4.1.2 would give an alert sound when the battery has reached it's full limit like Gingerbread used to do.
Who would be the best place to ask them to do this on their next update?
But I think that it does..a very short one indeed, but it does, along with the screen lighting up briefly..

are you using custom battery ? like double-powered-battery
So, I was reading up on ART vs DALVIK and decided to switch to Art to test it out. Well, after switching I noticed that my battery went from 80 percent with an estimate of 7 hours and 41 minutes to 80 percent with an estimate of 2 hours. I decided to do a factory reset and am still seeing that it has a low hour count anywhere between 1 to 3 hours. Its been about 30 minutes and the phone is now at 68 percent. At one point it went back to 7 hours, but went back to being 1 hour and 4 minutes.
Any advice would be greateful!

First off stop looking at the estimated time left cause it's never correct and means nothing. If you truly have battery drain then download wake lock detector or better battery stats and see what's eating your battery. But you really need to let your battery set in a few days before you start getting worried about if you truly have battery drain.

It's been correct on my previous LG (Had it for a few days before exchaning it for a new one due to heating problems) This one was also displaing it right until I switched from DALVIK to ART. After I switched back, I was getting a major battery decrease. Was also doing it with the other G3 (In the process of sending it back) so I left them both alone and eventua;y the estimate went back to normal, back to about 17 hours.
ANyways, thanks for the advice
I downloaded wake lock from playstore and greenified apps i saw waking device up i have better battery life now I also undervolted -72 globably and put cpu to 12,000 something on faux clock as well as dancedance governor
So I updated my phone tonight and after it used 30% in an hour or so. All I was doing was using FB on it. Prior I played PAD for 15 minutes and it hardly used 5%. I've wiped cache, cleared app cache, and now I'm working on a full discharge from 100%. The battery is brand new and it was getting better life prior to the upgrade. So much for 3x better battery I guess?
After clearing caches I left it idle ofer night. It used 13% for 20 minutes of screen time. and then it used 3% idle over the 5 hours I slept. Still seems a bit high on usage for screen time but idle is great.
So I discharged it completely and now its losing power fast again. The battery was 100% unplugged it and turned it on and its 97%. So I turned it back off and checked it and its also showing 97%. Charge it back to 100%, turn it on, its on 100% but loses 1% in a second. Plugged it in while onand it took like 3 minutes to charge that last 1%/ No idea why. The battery is brand new and got 2 or 3 days on idle before, now it reports 20 hours. what happened to that 3x better battery? What else can I do to sync the battery properly? I also noticed 100% is not 100% until the phone tells me battery is charged.
Again this battery is brand new and my life with 5.1.1 was pretty good.
I've been having poor battery calibrations in EPH7, though my battery is still what came with the phone.
There are days I can get to about 5? left before the phone dies, and there are days it dies at 15?..
Already tried charging all the way till full while the phone was off, still the same. It's random, but I just generally expect the phone to turn off as I come close to 15?.

That sounds like a bad battery. I can get my phone to drain down to 0% before it dies, but the battery usage can be erratic.
After some testingm the first 5% (95-100%) does down fast but after that it can go a pretty good while. Not sure why. I left the screen on with max brightness, turned on NFC/wifi/bluetooth and just left tons of apps running and it took 4-5 hours to get the battery down to 20%. the life is in fact great just not properly synced. No root makes it more of a pain to calibrate.
So I charged the battery offline and it got to 100%. I switched it on and it shows 97%. What the hell has marshmallow done to my note?
last post. If I charge the phone formt he OS it reaches 100% seemingly properly and doesn't discharge quickly. Not sure what marshmallow screwed up.
I had the same issue with my battery draining quickly after the upgrade. I backed up all of my data and then performed a master rest of the phone and then went into recovery and cleared cache as well. Once it booted back up I reloaded all of my apps and reconfigured all my accounts and my battery acts normal once again. It was a pain in the ass to do all of that but it did work for me so hopefully it works for you too.
