How can my battery life decrease so much for no reason. - HTC Sensation

I used to get about 10 hours from my battery, i've installed no new apps or anything in the past few days and all of a sudden i can't even get 6 hours out of it, this is on an Anker 1900maH battery. I wouldn't mind if i'd been using the phone heavily but it's just been sat on the table, as usual it just says that the display has been using the most power.
Any ideas why this has happened all of a sudden?

How were you only getting ten hours from an Anker? How much screen on time?

Kill off the HTC stuff.

HTC stuff and syncs.

custon rom , htc's rom is very poor. Have faith in our devs here, they will do you proud.

Why are you guys assuming he's on stock?

I've always been interested in rooting one of my phones but i'm just worried i'd end up bricking my phone, don't have much luck with these things you see haha.

because Stock = **** battery life.

I don't get it, I get great battery life
I get around 2 full days on an Anker with light usage. I can easily charge every other day. I unplugged this AM at 9:00, I have 15h 37m on battery now and have 75% left. I leave wifi and 4g and gps on all the time. I did turn off the HTC stuff and replace launcher with Launcher Pro. I've rooted it, but always got great battery life since the first week.
So why do I get about the best battery life I've ever had on any Android (G1, N1, and the Sensation) while folks here get much worse?

Yes, I have gmail and k-9 (imap) on push. But they take hardly any battery according to SystemPanel (which is awesome btw).

Have you tried using Battery Calibration from the Android Market?

G2x Battery Life?

What is it like?
For now is 2 short
Waiting to see this myself, but truth be told, I had horrible battery life on my other Android phones, G1 and Nexus One
My nexus s has great battery life
Nexus S
I'm sure we wont know for a week or two because the batteries take some time to get used to cycling . I hear the o2x gets a day-a day and a half and they have stupid lg bloat processes in the background as well as crappy email services
I think it will take 1-2 weeks before we can fully test how long battery life is. Initial battery life out of the box is expected to be bad. We will need some charge-discharge cycle first to fully calibrate the phone's battery.
I expect batt life to be bit better on g2x than stock O2x cause it has less bloatwares and it is running on stock android froyo.

I am quite impressed with the battery life so far, and coming from a Nexus S that says a lot. I'm going on 14.5hrs my first day of full use (light to moderate, I was working all day) and have 23% left. I wish it had 2.3 so I could post a graph for you...oh well.

I use titanium to freeze bloatware. I did not delete them to allow OTA updates - if ever 2.3 or 2.4 show up.
It very depend how u use your mobile, if I dont play games at all just call and text plus some weather updates trought wi fi or gsm, phone hold for me up to 3 days, but is very hard to dont play games on it (phone not rooted,standart lg soft 10b)

mission complete. i laughed lol
Just ordered mine
I hope its better then my Nexous one (last all day easy)
Second full day of usage on my G2x. It did not make it though the whole day. It is miles ahead of the Nexus One, and EVO (which was garbage). However, it definitely cannot compete with the Nexus S in this department. Only time will tell how much is hardware and how much is 2.3.3.
I have a feeling most of it is software. On my G2x the majority of the battery is consumed by Cell standby and Phone idle, as with all other pre 2.3 devices I have used. With my Nexus S the Cell standby and Phone idle use much less battery which I would assume is attributed to software improvements. The display uses most of the battery (and the display is very efficient since gingerbread has a dark interface with the NS samoled)
I don't have specific numbers handy but would be more than happy to post some if anyone is interested.

What's the proper way to do this? No instructions out of the box...
The first two days, the batter life was horrible. Once the battery dies, and was charged a couple of times it got better. I also used setcpu to underclock which probably helped a little.

I did not know this. How does not having some apps prevent OTAs?
while using set cpu is anyone having a issue trying to select the scaling governor? its not highlighted on my g2x so i could put it on demand!

Battery issue?

Purchased this morning and the battery was drained... Fully charged at 5:30pm. Now at 7:30pm im as 50% with minimal use. a 4-5 hour battery life is not going to cut it.
Hopefully this is just an initial charge issue, but my vibrant never drained this fast.
Worried!
U may actually have a bad batt. But id give it a chance. Drain it down to 0. Turn it back on. Let it die again.
Then charge it while off. If it happens again youll know.

I have done a few charge cycles completely draining it and battery life is still pretty bad...it better get a lot better than this or it is going back.
Also getting random freezes and reboots.
I've got a ton of apps and widgets installed and use Exchange push. Battery life has been just a little worse than my G2. The phone froze after I first configured it and I had to do a hard reset and rebuild it. It runs a lot better after the reset. You might want to start-over and see if it make any difference for your freezes and resets. I'm purely guessing it may be the difference between the phone configuring the SD card and reading off of one that's already configured.
Bad batt. 4 hrs is a wayyyyy bad.

Sounds like my experience too. My battery yesterday lasted me no more than 7 hours. Wooh, I was pissed. So far today though, It's been on for 14 hours and I'm only down to 25% with some medium-to-heavy emailing and texting, and a few 5 minute phone calls. I'm very impressed after this second charge. I'll drain it again tonight in hopes for a little additional life. Stick it out for another day or two, OP.
I'm really concerned because I've had my phone since Monday and have charged it at least twice a day. It's not getting any better :-( I have even froze alot of the bloatware and apps that run in the background. I can't handle 6hr battery life :-(

You mean for an exchange? Or ask for a new battery? Will they do that?
I also have serious battery issues. The battery usage is mostly consumed by cell standby and bluetooth. On my mytouch 4g at most these parameters were a few percent each. On the g2x they are like at 25% usage each. This does not appear to be normal. This is with minimal to no usage. I dont get it. Is it a software issue, there is no reason cell standby and bluetooth should be usaging so much juice with little to no use.

Root your phone, after that install Titanium Backup from the market, and once you load titanium backup, you can actually go to Backup/Restore and find the app that you want to freeze, click on it and choose Freeze.
Once you install Titanium Backup - it will ask you for root rights - click on "yes" or "allow" (dont remember exactly which one it was" so you can provide root rights for it.
Anybody know of documentation on best way to calibrate the battery? I did 1 discharge - charge cycle... how many more do I need to do? Do they need to be back to back or can I keep it plugged in while using it today?

My battery lasts a little less than my NS or vibrant. It should at least give you 5-6 hours of HEAVY usage. I left the house yesterday at 10 and by 6 it was done. Since it's a new unit I used it heavy, plus I rely on it for scheduling and contacting clients about every 30-60min. I was also playing games on my breaks.
You probably have a bad battery.

I do seriously think that there are a lot of improvements that will come in a software update. The Cell and Wifi usage are ludicrous and it's probably a matter of getting the phone out the door with an update to follow.
This is only the second Tegra 2 phone to be released in the US.
2nd day with the G2X and the battery life isn't getting any better... If anything it's getting worse...
90% at noon and 20% at 2:40pm. Plugged in at 2:40 and now 20 minues later im back at 88%
Drains way too fast, and seems to charge even faster...
This phone is faster is every way compared to my vibrant, I just wish this wasn't true for the battery loss..

Tips to GREAT Battery Life!

Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you
I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too
Edit - Updated with more recent stats

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.
Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..
I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...
Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.
I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.
Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours
neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.
Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.
Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.
you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.
My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.

Anyone having crappy battery life with ICS?

Just curious is it just me or does the Skyrocket have ****tier battery life running on ICS compared to it running on Gingerbread? Anyone else having battery problems. I've been running ICS on my I727r for 2 days now and the battery life is very questionable. Probably a battery stat reset will work :S

Yeah, my battery went out pretty damn quick yesterday, but that could be because I've been fussing with my phone more than normal.
The first day of using ics my battery life was okay. The second day my battery life sucked. Why? Because I set up Facebook. Battery manager showed 10% use and I hadn't even checked it. Its the bloat!

Same, my i727r battery life is horrible since i flashed ICS.
I have noticed that my android system is pulling a lot of juice compared to GB. I made some changes today like freeze all the bloat + installed UCLC4 modem. And wiped battery stats + complete drain and discharge of the battery. Lets see if it get better after a few cycles.
My battery seems a lot better! Way way way better. 25 minutes of web and its still full!

Battery has been much better for me with ICS.
Freezing tons of bloat helps..
My battery life has been horrible on ICS but when I look at the battery thing, Face Unlock used 35% of my batter (when my batter was 5% left) o-o it takes THAT much?
My battery life is absolutely amazing with ICS.
I have the stock rom debloated completely, and a lot of junk is disabled. Coupled with turning off auto brightness and leaving data off when i don't use it, the battery just chugs along.
This morning I got in my car at 7 AM, started playing music full blast through the stereo for an hour. Got to class, played some temple run, approximately a half hour worth. 30 texts or so, one 1 minute phone call. (data was off the entire time, it keeps facebook from butting in from behind) My battery has literally only gone down 10%, and it's 1 PM
I'm in love.
Seems fine here, I usually have it plugged in but today am testing it without. The couple charge blips are from when I had to get some files off of it.
I froze a bunch of the AT&T bloatware, have had Wi-fi, BT, GPS enabled the entire time. Moderate/light use... I've attached some screens.
I'm running http://forum.xda-developers.com/showthread.php?t=1567817 with the flashable ICS modem.
My battery has been horrible but it's only been a day for me and my signal has been fluctuating a lot on day one. It's stabilized now so we'll see after a few days of use. But right now it is horrible.
It seems mine is doing worse.
But I have been adding a lot of stuff since this is my first time rooting.
I am about to get a battery depleted(at 12% right now) and reset the battery statistics and install the OEM battery.

I thought there was a lot of debating over deleting the battery stats, i remember an article from a google programmer saying that it actually decreases battery performance...i personally stopped doing it a year ago and noticed a better batter experience, most of the time bad battery comes from a bad flash or apps that run in the backround and use location services
My battery life was horrible with ICS so im back to GB. At work with phone in pocket for 2hrs and was already down to 75% off killing battery and charging it fully next day. When I got home after 8hrs of work already at 50% and thats when its in sleep mode. Using it I would drain 1% every couple minutes definitly bloat. Might try new debloated ones but kinda skeptical since GB gives me amazing battery life.
Once the kernel source drops custom kernels will make all you guys stop crying your all used to optimized stuff not samsucks stuff lol give it time

Well condiering I have never reset them and did this first and only flash of the ICS leak, I'm hoping it helps out. We'll see what happens.
I have Juicedefender turning everything off while sleeping(set widgetlocker to deinied so when locked, widget locker stays active to be ready, and juicedefender see's that and turns off data)
On my 2100mAh nexus battery I barely got over a day(was getting 36-40 hours on GB)
Either way, I have two batteries so I'll deal with it until either an official ICS release or a new rom with better battery performance comes around.
I also have the nexus battery. Def have less battery life with this version of ics .
It could be the algorithm the use. At the start of the day is slowly draws down. As the day goes on it seems to drain faster

Actually, I have been having the Best battery life to date. I will post my list of APK's that I removed. I don't do FB or anything like that, so not sure if that is affecting it. Also, in a non LTE area. on the UCLA3 kernel, I was absolutely getting horrid battery life.
I live in an LTE area and I am getting almost a full day of use. Never got that with GB. I keep wanting to charge it, but I dont have to.
I do have Juice Defender running though, and it disables my data in 15 or 30 min intervals when the screen is locked. And I have SetCPU which limits the CPU to a max of 384 when the screen is locked.

Yeah this phone gets way better battery life than my s4 did with same size battery. Love it. Does greenify really work that well? I have never used it as I have great battery life without it.

Lots of reviewers are talking about how the M8's battery lasted longer than the S5 too. Samsung needs to stop slacking on the software and give us a lightweight touchwiz. I absolutely love Sense 6 and I'm usually an AOSP guy. I'll probably try out GPE Roms once they're stable but honestly the new sense is everything I want out of android software. Minimal, clean, customizable, smooth and fast.

CWM. Always been wary of TWRP. Not sure why.

Twrp here. I've always been wary of cwm. Lol. No joke. And yes, the battery on this is ridiculous! I used the ONE MAX today to do a test. And we all know, it Has a bigger battery, 3300 mh. The M8 beat the MAX. Did the exact same things throughout the day, and no lie, the M8 won the test.

I don't think I could ever kill this battery in one day unless I was using navigation alot or constant gaming. So far today.

20 hours and 55% full over here on just regular power save mode and SkyFall
Don't get me wrong, I'm getting great battery life as well (though coming from a VZW GNex, anything would be an improvement). However...posting screenshots of how long your device has been off the charger with no other information (screen on time, app battery use) doesn't tell us anything.
Hell, I could leave my phone at home on wifi with the screen off and not touch it for the next 3 days, take a screenshot of any remaining battery life, and post it being like "OMG I got 3 days of battery life, this is amazing!" And it would be just about as informative and truthful as your screenshots (not including yours Evocm7, obviously).
sorry im kind of a noob i am aware of greenify i have used it but whats skyfall? I tried searching but nothing is coming up but james bond.
EDIT: Sorry havent looked at roms yet im just rooted atm

I hear what you're saying. Personally, I'm not trying to participate in any scientific study on the matter. All I know, and all I care, is that I've had the phone off charge for 29 hours now... using it the way I normally use it during an average day ( pretty light)... and I'm still at 40% battery.
Coming from a malfunctioning POS Droid Charge this phone is a godsend. I used to have to carry an extra battery just to get through an 8 hour shift at work starting on a full charge.

lol I came from a GNex, so we're probably in the same boat. Even on wifi with extremely minimal use (10-15m screen time all day, which with how slow and laggy it was I didn't really care)), I would be down into the 60%'s by bedtime. If I went to the gym with full battery, after listening to Pandora while doing weights, and watching Netflix during cardio, it would be into 20-30% by the time I left, total of maybe 1 1/2 - 2 hours.
I flashed Skyfall the other day after charging my phone to full, and by the time I was done flashing, re-installing everything from TiBu, updating a few out-of date apps, and setting everything up, it was down to maybe 95%. And that was with the screen on for probably 20 minutes straight.

I think taking into consideration the snapdragon 801 chip how it saves battery, sense 6 being light weight, if one needs to you have the choices of battery save mode and if that's not enough extreme battery save mode! This phone came built up from the floor up. Now if we just had the 1.56 software version with all the above included stock and operating correctly, I'm sure we would see even more battery savings!
Im looking for good app for monitoring battery use. Is betterbatterystats the de facto standard?

There are very few "de facto standards" for anything in the Android ecosystem...which is why we like it. I use a combination of GSAM Battery Monitor with the root companion, and Wakelock Detector.
Dont get me wrong, I get decent battery life, but nothing like you guys. For those of you with amazing OST are you guys using Google Now? I just installed wake lock detector to see what is causing my batt to drain more than others.
