Hey folks,
So I'm shooting for good battery life as my #1 concern with my phone. At stock speeds with a good kernal and a debloated rom, the performance is up there and the phone snaps along just fine for my tastes.
However, I'd like to try and maximize my battery life.
Upon a fellow member's recommendation, I installed 'CurrentWidget' and now have the current draw updating directly on my homescreen.
BUT, I don't really know what I'm looking for as far as analyzing what is using what, and what are good numbers.
The phone updated the widget once when the screen was off and it was 40mA.
When the screen is on it goes from somewhere around 250 up to over 700.
Anyone have any tidbits of info for me? Let's get a discussion going.
Thanks!

40 mA is normal for a TBolt with the screen off, that's what most of them I've seen run at. Over 700 during usage seems a little high, were you doing something demanding? And check your brightness settings too.
If your ROM has Spare Parts installed, you can go into Spare Parts -> Battery History and check various usage statistics with the drop down menu. Particularly useful here is Partial wake usage, since that tells you what's draining your battery while the screen is off.
There are threads all over the place on battery life, so you should definitely search for them.
34mA is about what i saw during idle time for 2 thunderbolts. but that is very high. other android phones like my nexus one and desire get 4-5mA over night during idle time, connected to wifi. so something is wrong with the TB stock ROM, but not much can be done unless you switch to cyanogen ROM or something like that.
also the other utility to use along with current widget is system panel, paid version, because it gives you a complete breakdown of every app cpu usage and what is hitting your device so you can troubleshoot and track your battery drain. that app is invaluable.
Mine also hovers between 30 and 50 on idle for two TBolts. I agree with the above that with a properly optimized rom we should be around 10 which will boost battery life quite a bit.
I use Battery Monitor Widget. I like it better than current and it keeps a nice history.
System Panel paid is also very very nice.
I'm having the strangest problem with my HTC Evo...
I used to get over 22hrs of moderate use (rooted) and ever since flashing any ROM running Sense 3.0 my battery life is affected to the point I'm lucky to get 6 hours of use. It discharges 15% within the first 10 minutes after unplugging the charger and continues to discharge at an increased rate throughout the day.
I unrooted the phone and took it to Sprint to "test" and after 3 hours they gave me back the same exact phone claiming they had "updated" it and everything, including the battery, had tested perfectly fine.
I feel like they are giving me the run around because obviously something is wrong here.
Any ideas as to what is going on here?
Rooting doesn't improve battery life, never did. Think of rooting as gaining admin privileges to a Windows PC, for example.
I think you have a background process running that is taking up a lot of battery, check the Battery Use page or reboot the phone.
I know, but it shouldn't diminish it either. It does gives you a chance to see a potential increase by undervolting, underclocking, ect.
Anways, no background apps running. All display scaled down, GPS off, ect, ect.
I have no clue as to why this sudden decrease in life. And Sprint says the battery is testing "excellent" as is the phone. Obviously something is not right here. Feels like they are being lazy and trying to avoid giving me a replacement.
Evo is known for bad battery usage. Best thing for you to do is get a backup battery.
Lol. I know that too, I'm not new to the Evo. I work with phones, Evo included, on a daily basis at my place of employment.
I'm saying this same battery used to last over 22 hours with moderate use when the phone was rooted and underclocked. Now the phone drains the battery amost instantly.
I refuse to purchase an additional battery to combat a problem Sprint should be fixing. I paid over $500 for this phone and haven't even had it a whole year yet. Something else is going on here...
Sounds like a rom issue, not a hardware one. Those sense 3.0 features and eye candy come at a cost.
Yeah. Sense 3.0 is a battery hog. Try cm7 or something AOSP

yeah, one turne off and reboot, Battery Life TERRIBLE too, i'm lost 10% when reboot

It's ture ！
Have you tried an app that shows you battery usage over your running apps? May tell you which programs are stealing all the juice
!. Rooting does not have anything to do with battery life...well..not directly..it depends on your kernels, apps, phone settings, etc.
2. I agree, Sense 3.0 seems to drain your battery a bit more than previous Senses... well...you know what they say, beauty has its price..about the AOSPs, they have better battery live but they are not so pretty as the Senses...again...beauty has its price
If it helps the 'Live wallpapers' are known to eat battery, but what it could be is Wifi, if you leave it switched on all the time it may be connecting to open wifi networks without you realising and eating the battery.
Interestingly though, a whole day of use, some wifi a bit of camera and some calls on a wildfire with wifi on, didn't seem to drop the battery much and this is with a rooted phone.
you can try green power
Even though it may sound lame to some of you, the app Juice Defender has actually helped extending the life on battery quite nicely for me...
Another possible route might be to try different Radio/RIL combinations, some can also extend your battery life.
Not to forget, as someone posted previously things like live wallpapers or background process. Task Killers have been known to cause battery drain for instance.
Good luck in your quest for battery life!

if you go to battery use in settings, youd probably find out whats causing your battery drain
I have a debate going on over at slatedroid and would love some of the hardware experts to weigh in. The other side who claims to be an android developer says that the phone apk's causing "cell standby" have absolutely no effect on battery life at all. From my experience with computers and from everything I've read I would have thought that because it's running constantly in the background it's preventing the CPU from throttling down and would therefore use up more power. But it's just a guess on my part. Is there anyone with concrete info on this?

Hey guys, I know hussainmicromaxa60 has recently posted a battery saving tip post, (copied from cnets post) but really what cnet said isnt of much use. i.e switching off GPS doesnt save battery as android only uses it when it needs to, the rest of the time its off anyway. So I thought I post a youtube video here with the tips I have found actually useful:
http://www.youtube.com/watch?v=sUAlbkvlVQ8&feature=youtu.be
The tips are to use programs like cpu spy and betterbatterystats, to find and stop partial wakelocks,
switch to 2g when you are near wifi
Use an app like screen filter when indoors or and at night
And finally check sync intervals for apps and change them to a longer time period.
Let me know what you guys things of the video.
best battery life
I have read the new forums that wipe battery stats would extend battery life. I have tried that repeatedly yet I'm not so sure that he does. The jury is still out on this. Perhaps someone that knows better can advice.
I have also read in some forum and I think this comes from T-Mobile, that wiping battery stats does not actually extend battery life.
The only certain thing is that if you want better battery life you must buy a better/bigger battery.
Well, I'm sure some applications can really help your battery (Juice Defender, Green Energy, etc..), however, I gave up all that and I'm using common sense (not a market app).
So, only use wifi when needed, wifi drains battery really fast. Same goes for the use of 3g. Sometimes it's like a taximeter when you turn it on.
Brightness, it does spend battery, keep your screen confortably visible but not on max brightness. Don't know how far "self adjust" works for everyone, but CM7 allows you to personalize the self ajudsting methoods more to your needs.
Voice calls don't spend much battery, what does spend is apps, games (specially the ones with nice graphics and stuff), network, and so on.
I don't listen to music on my phone so... I'm not sure how much battery it takes to use it as a mp3 player, however I have an iPod for that, so I avoid listen to mp3 on my phone.
GPS... hardly use it... only when needed.
So, for all the "extras", only when needed seems to to do the job.
Also, disable "vibrate" when you don't need to. Like, cm7 vibrates on some awkward ocasions, like when you pick up a call, hang up, etc... if you don't need it, disable.
It's really personalizing your rom options to the point where you don't need additional features just for the sake of having them turned on.
Use your phone and features on a "when needed" basis and your battery life will be be longer.
Also, widgets, they do use battery, and sometimes, more than needed. The ones that use Internet (wifi or 3g) use more battery. Facebook, twitter, etc...
One more thing, about the CPU governors this time. I usually keep mine on a on-demand. When it runs low (under 20%), it switches to "conservative". It does get sluggish, but you get a few extra hours out of it. It's usefull for emergency voice calls.
Try to "underclock it" when not using (screen off, charging, etc..) and use overclock if you're really sure you need to. Most of the times the max allowed cpu without overclocking is more than enough, unless you're a performance maniac and need the best of the best performance out of it, there's really no need to overclock it.
If you play a lot with your phone (like me), at least keep a usb cable or a charger with you.
Hope it helps
PS - Some apps allows you to customize the way your phone spends battery. I find Juice Defender really cool for that. Spend about 20 minutes tweaking it for your needs, and the next couple of days with final adjustments and you'll notice improvements.
nice

I have tried several battery saver, but all the same .. no one gives optimaliasasi on my samsung.. sorry for my bad english
wiping battery stats will not improve battery life.
screen brightness is the major reason for battery drain. so keep the brightness as low as possible

Things like juice defender ect can be helpful i guess but i have never seen much of an improvement, in terms of wiping battery stats, all it really does it to allow android to read with better accuracy the amount of juice you have left, so it does not increase battery life at all.
Things like cpu governers etc is quite advanced, and I dont know really much about it, but as long as you keep under control misbehaving apps, switch to 2G when needed and dont have apps checking every 15 minutes for new data, you can get through a full day, no problems.
Also, keeping your battery in good condition always helps. First few charges, charge overnight, first week or two never let it go below 50% charge, and keep total discharges to an absolute minimum, and you should have a battery that wont degrade too quickly.
Hi everyone!!
I'd like to get some advice about my issue that I've been having for a while...
My battery drain is what you may see in my attachments. Please tell me some good advice to reduce this drain or whether it is normal functioning either...
In conclusion, I'd like to know if it might be convenient to replace the battery and, furthermore, whether there are larger batteries with more autonomy.
My phone is 2 years and half old but to be honest I use it intensively with its battery-case (manufacturer: Newdery).
Thanks!!!
Sorry for late reply, just saw this.
You get 6 hours of battery life with 14% screen on time? That doesn't sound to correct.
My suggestion would be to install the app: AccuBattery. I swear by it - it is very good I think. It will watch your apps much better than the stock android battery monitor. It will also tell you your battery health, the mAh left out of the total of 4000. If you have a very low amount left (capacity wise) then you may want to get a new battery. But make sure to do several charges before taking it as accurate. Use the app for several days, even the little "notes" in the app will tell you this - it's to "acclimate" to your use and give you more accurate statistics.
Hopefully this helps - 6 hours is definitely not good.

Hi!!
Thank you very much for your reply!
I forgot it but I already had Accubattery installed on my phone.
In fact, in attachment you have the battery wear data from April 2021 till now..
I hope that I shared you useful data to analyse the issue.
What do you think? What should I take from the app?
I thought that the new Android version 11 is the cause of battery drain as another phone (Xiaomi Redmi Note 10) suffers from it after the upgrade to Android 11..

No prob
Could you take an [extended/full] screenshot of the "Discharge" tab? That will show more info about which app is draining more. Also those numbers change I believe on every charge so you'd have to just keep an eye on which app is always at the top of the section under "Foreground App Battery Usage > Battery Usage" section. Hopefully it isn't just "system" or something, hopefully it is an app that you can remove/freeze.
And what does it say for Battery Capacity above the "Battery Wear" chart?
And speaking of the wear chart, you'll want to stop charging all the way to 100%, it looks like you're putting over 1 cycle of wear on the battery very often which will degrade the battery quicker. The 'Charging" tab explains this even allowing you to set a reminder to unplug at a certain charge level (it tells you the higher you charge the more wear you put on the battery - unfortunately that's how batteries work).

Hi, thank you for your reply!!
I'm sorry for my late replies..
In the attachments you have what you asked me.
It seems that Facebook drains the battery a lot despite the fact that I don't use it much.
The battery wear seems to be almost one fifth of total capacity for a capacity of about 3200mhA.
I'd like to have something better...
I have set at 83% the alert to reduce the wear of the battery but I wonder how it could work fine when the phone is turned off..
No problem
So, I'm not exactly sure how you use your phone but it looks like the screen-on at 23%/hr looks pretty bad but then also it says combined time was 102 hours? I believe that means how long it's been off the charger. If that's the case you can't get any better battery life than that, that is really really good.
You mention facebook doing a lot of draining. Try researching a good app freezing option on the app store. I only did a quick search but this one came up: https://play.google.com/store/apps/details?id=com.catchingnow.icebox but read the reviews (I did a quick scan and it looks like it might work as intended) and look around maybe there is a better one. But the point of this is, to freeze any apps in that list (the accubattery foreground apps) you barely use and it will prevent them from running in the background. This will definitely give you better battery life.
And I don't see the deep sleep statistic, is that around 90hrs along with the screen off time? It should be more than the screen off time at least, because if it is then it is deep sleeping correctly (no rouge apps causing it to not deep sleep), but if it's less than the screen off time, then something (maybe facebook) is keeping the phone awake even with the screen off, causing extra battery drain.
And 83% charge is pretty good, maybe even 75% might be better, I think from 0 to 75 it's like .3 or .4 wear but it's like with these batteries once you start going over 75% it jumps in wear dramatically. And if the phone is off (turned off completely you mean?) then the battery won't gain any wear because it won't be in use at all.

I noticed that I didn't make all the screenshots, but now I've just done them with regards to this new discharge cycle and you have the deep sleep statistics for a better analysis - they are in attachments.
I asked here for a longer battery lasting and instead I set it as 75% as the maximum percentage value of charge that reduces my autonomy but saves the battery.
However, yesterday I noticed that the charging wasn't deactivated when the phone reached 80% of charge (is the value that was set yesterday). Oughtn't Accubattery deactivate the charging?
The statistics you mentioned in your previous post appear to me a bit awkward even though they are related to many sessions in the last 7 days.
I use my phone with my phone case-battery (Newdery manufacturer) and until few months ago it could charge the phone up to about 80 % when I couldn't charge my phone through its charger. I need the charge to last a day, almost 20 hrs…
I noticed that the phone started to wear - the last few months - when I noticed that I couldn't have the phone working till the late evening and I tried to charge it fully before I left my house...
However, it is clear what I need for my use and habits, thus, new reliable battery-case suggestions would be a good hint for me...
In the end, I don't know what to do about apps that manage the apps freezing because I don't know how Android allows it and if it is worth it..
