battery life

anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.

See my post here:

Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.

I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.

Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.

Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.

I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.

I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.

I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.

My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.

I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.

I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.

heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life

Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.

It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu

BATTERY Performance / Expectations

I'm just wondering if some other Sensation owners can chime in with their battery stats. I've had the phone for a couple of days now, and with a few battery cycles behind me, I'm still concerned. I do understand the "new toy factor" of using a new gadget much more frequently than normal, but what specifically concerns me is the amount of juice the display is using. With push email on, twitter sync on, auto brightness on, and mostly indoor use, I am finding that I can't get more than 3 hours of Display On time. At the moment I have the following stats:
17% Battery Remaining
9h 5m 9s on battery
Display: 80% (Time on 2h 7m 31s)
Cell standby: 8%
Phone idle: 5%
Wi-Fi: 5%
Maps: 2%
Usage has consisted of some light web browsing, just a few minutes of phone calls, lots of texting / email, and general playing. At the moment, I can barely make it to the afternoon, let alone a full day. Is this comparable to what most of you are seeing or do I have a bad battery? Coming from a Samsung Galaxy S I was hoping for better performance but so far this is far worse ( I used to get 5+ hours of Display On time )..
Thx..

45% remaining
On battery 6 hours
Display on 2hr 10min
Display 85%
WiFi 6%
Cell standby 6%
Phone idle 3%
Comparable to my DHD I'd say, possibly a bit better. Custom roms did improve that though
Funny thing is my girlfriends galaxy s has shocking battery drain, particularly in standby. She's currently on Darkys ROM and I've given up trying to figure why she can never last a day with her phone.

Coming from a G2 and this phone seems to be much worse. At work I would make it through the afternoon with very minimal usage mostly idle and checking my email on it 8-10 times and have 80%+ left over when I left the office after 9 hours off the charger. Even mostly idle I'm at 50-60% during the same timespan with a 20% bigger battery. Yesterday I was @ 95% and used the GPS for 30 minutes and it dropped the battery down to 60% in that small time period.

My batyery sucks big time... I trained it once - didnt do anything. Still get about 8 hrs between 7am and 8pm. Light to moderate usage :-(
Maybe i should look into finding a bigger battery

I get about 14-17 hours, depending on usage. I'll post my stats later today as I'm at 100% right now.

I would disable htc hub from syncing. It syncs every few minutes and drains the hell out of the battery. I also disable always on mobile data and that helps save the battery when my phone is idle but things that you auto sync might have problems. My .02.

This is pretty much my usage.
I can get over 24 hours pretty easily if i'm only using it for a phone call here or there. This is with Wifi turned on(and wifi calling on), auto-brightness, and auto-synching set to different intervals. Exchange email is set to every 15 mins, google set to push, FB is manual, weather is set to once a day.
If I'm using it pretty heavy, browsing the web, playing a game or two(peggle & plants vs zombies), I'll get typically around 12-14 hours.

For the first few days the battery life in my brand new Sensation sucked too. I was getting maybe 8-9 hours of moderate usage before having to plug it in to recharge.
On Friday night (June 24th), I did a full factory reset through the bootloader, installed Juice Defender and set it on Aggressive setting, and charged it overnight for about 8 hours while the phone was turned off. Yesterday (Saturday, June 25th) after over 18 hours of moderate use, which included many phone calls, emails, some texting, browsing, playing with the phone, and even a little bit of Stupid Zombies, the battery was still at 42%!!!
I charged it overnight again for 8 hours. So far today, after 3.5 hours of HEAVY usage, the battery is at 93%. I am beginning to like this a lot!

Email auto-sync, BT on at all times, some internet radio streaming today and still at 91%. It's been off the charge for 3 hours now. I think that's pretty good compared to my HD2.

I have been very happy with the battery life so far, its better than the battery life was on the MyTouch 4G I had. Can go a whole day no problem, MyTouch 4G couldn't make it a day....

To all you guys that are getting phenomenal battery life, could you check your battery stats and tell us your display usage?
Thx

I will post battery stats later today but battery life has not been as good as I hoped. Compared to the G2x I'm getting worse battery life. Then again, it's too to compare a device that is running a custom rom versus stock.

Not blind ... are you looking for awake time?
3 hours 11 mins

So with 48% battery left your display had been on for over 3 hours? That is excellent.. Definitely something wrong with my battery if that is the case.

Yup. thats what i read... maybe i should tell you what I did when I got the HTC Ssensation...
I used it and set it up on that batt level that came out of the box... till it switched off... kept if off and charged it the whole night.. about 7 hours.. unplugged.. turned the phone back on.. used it again the whole day and brought the battery level to about 19%.. turned it off.. charged it again full for about 7 hours... and now i am using it as normal!!
EDIT::: hahahahahhahahahahahaha.. no wonder... I am sorry.. its a typo.. 2 hour and 11 Mins.. well now 18 mins!!!
Still quite decent I think.. with the usage!!!

My battery sucked too but its doing much better (ibwas not worried because the same happened to my nexus one). Always moderatevuse and I get about 16 hours of use and still have about 40% left.
I have auto sync on, wifi off, screen brightness on about 60%.

This is probably the longest lasting device I've used in a while. My G2X would get me about 11 hours with moderate use but my Sensation will last close to 16 hours with moderate use.
The only thing I have syncing is my Gmail account and calendar. I turned off everything else including weather. I also never keep my display set to automatic since that's just another piece of hardware that constantly has to work. Unless I'm in direct sunlight, my display stays at 50%.

Battery life question

I recently bought a g2x. I previously had a Optimus v with cm7 that I liked, so I pretty much immediately installed cm7 on my g2x. I've noticed my battery will drain 25% on stand by overnight. Just wondering if this is normal, and if the stock rom is any better in this regard?

Well...its normal but at the same time its not, and i'll tell you why. Mine drains about 5-10% overnight (around 7 hours) and with wifi on it is usually even less, about 3-5%.
Though there HAVE been instances where it has drained about 20-30%, usually I just pull the battery (or restart the phone a couple of times) and it seems to fix it till the next time it happens.
In fact just last night it drained 35% =\ but normally it is around 10%.
Im on weapon G2x

My phone drains about 3% overnight. Wifi and data off. CM7 with Faux kernel and setcpu screen off profile.

It honestly depends what kind of network signal you're getting.
I've had mine drain a considerable amount one night just because I had low signal. Especially when you have low signal AND data on.

Mine drops 5-10% at night, sometimes less. I either keep it on 2G with data off or wifi with wifi calling on. Wifi calling seems to save a ton of battery.
But, leaving data on and 3G on I drop 30% or so.

yeah, as everyone says, depends on your usage (and/or signal). i've gotten 12h, i've also had 4 days, it really differs on lots of factors.

Battery Life Question.

Hi everyone,
I noticed that my One X has been losing about 12% of battery life while asleep for 8 hours (while I'm sleeping). Is that normal? How much battery life do you lose when you don't use the phone? I leave wi-fi on and that's about it. I checked to make sure that the phone isn't awake during this period.
My battery life has been good on some days (lasts about 20 hours) and bad on some days (lasts about 10 hours) with almost identical usage. Any tips on improving battery life?
I went camping and put my phone on airplane most 80% of the time except when I needed it. It lasted me nearly 3 days! Does LTE consume a lot of battery power? Does wi-fi do also?

Yes to both of your final questions. LTE uses a ton of power. I went to the San Jose area where it's only HSPA and my battery was phenomenal. Wifi may drain significantly if "best wifi performance" is enabled in advanced wifi settings.
Check what uses your battery overnight. What process does it say under power in settings? 12% for 8 hours isn't really that bad..

Wifi consumes the least power of all, but like the post above says, if you have "maximum wifi performance" enabled in your advanced wifi settings then it will prevent your phone from going into deep sleep and drain more battery than it would if that option was not checked. Overnight I usually drain about 1% an hour or less (on both CleanROM DE and AOKP M6.2).

I think it's not LTE drains the battery. It may be because of searching of networks when signal on LTE is bad.

It's sort of both. When you have a good LTE connection while using data then it uses up more battery or if you have a poor connection without using data you will use even more battery or if you have a poor connection while using data that would be the worst for battery. But if you are in a good coverage area and not using data then the battery should be fine.

Drain of 12% over 8 hours (1.5% per hour) of screen off time is pretty damn good. Certainly nothing to complain about. I get somewhere around 2.5% per hour overnight.
Phone battery last forever when in airplane mode. The phone radios are a big consumer of power, often second only to screen-on time. Way back, I had my old HTC Tilt2 in airplane mode in a location with no cell service (basically just using the phone as a watch and camera), and it was on track to last about a week (maybe more) before needing a charge.

12% is what I get overnight. But If I turn off WiFi before sleeping then I get around 5% loss so turn off WiFi if you need more battery.

I feel that most people would get better battery with WiFi turned on. It seems the area you place your phone overnight is not getting a good WiFi signal and/or you might have some of your settings to sync or download while on "WiFi Only".
It varies from person to person and it usually ends up being something in the settings, specific apps, and/or quality of connection (mobile or WiFi).

Cell standby draining the battery. Anyone notice?

Hi, I just got my U11 and using it for 5 days now. I notice that when I leave the phone at night, the phone lost battery around 10% everyday. From the battery stats, it said Cell standby is the most hungry one. Anybody found this issue?

I noticed it too, 40% battery usage was cell standby... ?

I'm seeing this too but I still get over 30 hours with up to 5 hours sot.
Guess cell standby is not draining battery, the rest just uses so little that this comes out on top.

Computed power use was 400+ mAh...

So what? I get 40 hours uptime and 7 hours SOT. The mAh reading is an estimation.

I also get standby or time without signal drain occasionally. running an unlocked sprint version on metropcs. hopefully htc releases some better radios in the near future.

Similar battery drain here for cell standby.
I'm on 1.27 stock rom.
Dual SIM with two SIM card active.
Any workaround?

Me absolutely same.. One screenshoot is on wifi second on mobile data.. Stock rooted ROM but same on unrooted

Someone has tried with Oreo firmware? Same drain?
