[Verizon Droid Charge] ¿GotJazz?:
I have a simple question: What is the biggest battery drain on your SamChg?

I'll bet that almost everybody out there though the same thing I did: "That gorgeous Samsung Super AMOLED(TM) display", right?

I mean, whenever I check the Android Battery Use tool, nothing even comes close: Usually, 78%+ of the power is going to the display.

So, if the SamChg batteries are so bad, and the display is sucking the battery the most, how long do you think the SamChg would last before dying if the SamChg had the display on full-time without turning off (Using StayAwake)? 1 hour? 2 hours? 3 hours?

How about: 8 1/2 hours!

I've done it with 2 different stock 1600 mA battery packs now. I've use the phone lightly during those times, so the phone wasn't totally idle (maybe longer life is possible?)

I've read that Samsung had really improved the power drain characteristics of the Super AMOLED displays, and now I believe it.

It also indicates to me that I probably won't gain much extra battery life from turning the display brightness down. I will keep it set on Auto Brightness now.

FYI - Right now, about an hour or so before the battery dies again, I am at: Display = 91%, sensorserver_ya = 5%, Android System = 1%.

I am suspecting the biggest drain I see during my work day is the switching between 1xRTT / 3G (and now, 4G networks) / No Signal - Which is a big battery drain problem I saw in the past.

Your thoughts?
[Verizon Droid Charge] Tornlogic:
I do know the battery use app in FroYo is pretty inaccurate compared to Gingerbread. It seems it throws any battery usage into the display row if its unable to determine where it really comes from.

For example, if you stream pandora all day with the screen turned off, most of your battery usage will show up as Display. Once I upgraded my DX to ginger, the same activity on my phone would have a much larger percentage of usage going to Pandora and media server, or whatever its called, and hardly any going to the display.... which is correct.

So if you use that app, take all that info for what its worth, until we get Gingerbread.
[Verizon Droid Charge] Cruiserdude:
That's great to hear, I'll have to give that a shot sometime. I will say that you are still better off with lower brightnesses, even though we don't have a backlight its still gonna use exponentially more power the brighter you go. But I wouldn't leave auto-brightness on, while the changing brightnesses don't hurt battery that much, the sensor to change them does, as its constantly polled. You'll see the sensor_server taking up a good bit of life.

Keep it on manual brightness, and just adjust it by holding your finger on the notification bar for a sec, the farther to right your finger is, the brighter it is. If you hold it you can also swipe back and forth to turn brightness up or down.
[Verizon Droid Charge] ¿GotJazz?:
Didn't know that trick! Maybe I should read the manual one day. :)

My thanks to you!
[Verizon Droid Charge] Yankees368:
Woah, that is an awesome trick! I have never even heard of that before.
[Verizon Droid Charge] mulk777:
Schweet! Thanks! That is a great trick. Another thing that I've been doing that has helped my battery make it through the day longer is turning off my mobile data. It only takes a second to turn it on when I'm browsing or using an app that requires the data.
[Verizon Droid Charge] Syn Ack:
Yeah, turn off data when you don't expect to use it for a while. Get a 4G/3G widget to switch between LTE and CDMA when you are constantly in a fringe 4G area and/or in an area thats 3G only. And I like the idea of the auto brightness thing. Froyo has had that brightness status bar trick since its been out. I used it a lot on my Fascinate. With 4G on constantly my phone drains 5% per hour doing very little. Its half that with 3G only or data off.
[Verizon Droid Charge] gman8966:
That is awesome! Didn't know that, thanks!
[Verizon Droid Charge] Homestar1217:
Info on this 4G/3G widget switch? I'd LOVE that, hate having to go into the setting to switch it!
[Verizon Droid Charge] zephymobile:
I'd like to know as well. All I can find are complete on and off data switches.
[Verizon Droid Charge] praveen1789:
this is cool. TY!!!
[Verizon Droid Charge] mrtruckincowboy:
I had the new leak go 17 hours and still have 40% left before i put on a charge I didn't use it much but it impressed me i got that out of it.
[Verizon Droid Charge] will2live:
Just grab LTE Switch form the Market. Put and icon on one of your desktop pages and it takes you right to the LTE / 3G Settings menu o you can switch it. IE no go threw all the menus to get at it.
[Verizon Droid Charge] lizardpro:
Also remember the screen only uses power when displaying white or color pixels. Black does not use power.

[Xoom Q&A, Help & Troubleshooting] SS2006:
Thanks soso much

Can u actually upload or attach the prop file itself

Copy and paste it to SD card if u need to
[Xoom Q&A, Help & Troubleshooting] rmcsc:
So... wait a minute. The WiFi version contains bits talking about Verizon. Anyone have any idea why?
[Xoom Q&A, Help & Troubleshooting] cam30era:
Here you go. My Xoom is a US Wifi only, running Tiamat ROM 1.0

Curious... XDA won't let me attach the file....
[Xoom Q&A, Help & Troubleshooting] bwcorvus:
I still don't think people understand. If you are running tiamat rom or tiamat update for 3.1 you are not wifi anymore. You are on a 3g system.

Here is the stock 3.1 wifi build.prop http://dl.dropbox.com/u/18315605/XDA/build.prop
[Xoom Q&A, Help & Troubleshooting] cam30era:
I suspected, but was not sure. That's why I stated that the build.prop was from the Tiamat ROM. Thank you for clairfying.
[Xoom Q&A, Help & Troubleshooting] bwcorvus:
No it doesn't. The build.prop from above is from a Verizon 3g xoom. Check the one i just posted, its a true wifi build.prop.
[Xoom Q&A, Help & Troubleshooting] SS2006:
Thanks to both of you

very much appreciated
[HTC Sensation] silentsnow31802:
My battery seems to be REALLY bad. Worse than most peoples from what i gather from reading threads. I get about 8 hours from a full charge with minimal use. It seems that my screen is taking up most of the battery, according to my battery use page.... Any one else having major battery drain like I am??
[HTC Sensation] kurtis.austin2:
My display is taking a huge percentage as well. Everything else is low percentages. Don't know why. My screen is always either on auto brightness or completely dim.
[HTC Sensation] vartanov:
Give it a while and a few recharges. It should get better. Same thing happened to me. It's slowly getting better. I have it about a week now.
[HTC Sensation] cheesinar:
I was getting 7 to 8 hours at first, had my phone almost 2 weeks now and am now getting just under 20 hours with moderate use.

Give it time. My sensation has far better battery life compared with my DHD.
[HTC Sensation] undercover:
Peeps, you missed most important thing. Look at the AWAKE line. Either OP is playing a lot with th phone, or something is not letting it sleep.
[HTC Sensation] bcpk:
Yeah, the battery really plummets when you actually use the phone (even on low brightness) but it idles quite efficiently at least...
[HTC Sensation] Gregory.u317:
Did u try juice defender? Just asking ify bout the sensation dnt knw either to get it or wait for sumthing else

mt4g royal ginger v2.1
[HTC Sensation] undercover:
Would help if you used proper language.

bcpk

Yeah, noticed same thing
[HTC Sensation] silentsnow31802:
I downloaded juice defender beta? whatever the free one was. To me that app does not have a good layout at all, either that or I was missing something. There dont seem to be any personalization settings at all. I dont trust apps to work when they just say "im doing something!!" ya know?

Now that I think about it on that charge I was playing music while I worked on my car for a while, that would explain the awake time. Even without doing that battery life is still really bad and the screen takes up 80%+. I will post another pic after my battery dies today. Dont plan on using it much so hopefully it will last longer.

That is good news about life getting better after a week or two though cause 8 hours with moderate use is unacceptable. My MT4G got a good 24 hours with pretty heavy use, I expect this thing to get at least half that.
[HTC Sensation] droopypillow:
i use juice defender and under normal use and a few hours of pandora streaming on wifi im at 35 hours at 40% battery
[HTC Sensation] m_speksnijder:
My phone was also drained like madness, within 6 hours it was empty, even if I didn't do anything with it. At the moment it is better, I did a factory reset through the startup of the phone (turn phone off, remove batt, place batt, hold volume down and push on/off button). There is an option to factory reset.

Strange thing was that when I turned off my phone before the factory reset, it was telling 34% batt. Right after the factory reset is was at 89% ???

I use Battery Status Bar app to display my batt in percentage...

But the good news is, my problem is now solved. Battery lasts for more than a day at normal use and 6-8 hours while very actively handeling it.

Looks like it was a reading wrong information or something...
[HTC Sensation] silentsnow31802:
Got 11 hours out of a battery today. So far its been charging for 4.5 hours and is at 94% charge. Takes about half as long to charge it as it does to kill it!

I will give juice defender a try. Seems like it works for a lot of people.
[HTC Sensation] Axefield:
I had same kind of long charging last night. Battery died at about 7:30pm. I plugged it and did not turn the power on. Went to play some ice hockey and after that I turned the power on again at about 10:10pm and it was still charging. At about 11:20pm(still charging) I unplugged for a couple of seconds to see the specs of the charger and then plugged back, surprisingly percentage jumped to 100. It was still on 100 this morning at about 8:00am.

Now I found out that phones own battery monitor tells me that time on battery is roughly 8 hours But when I check the time from Battery Indicator it tells me that time on battery is roughly 15 hours, which is correct.
[HTC Sensation] poisike:
Seems that a lot of people are getting false battery readings, me included. I did a factory reset last night and this seemed to fix this, at least until now it seems to report correct (realistic) values. I haven't charged the battery after the reset so we will see if charging messes it up again...

I hope this is a software problem, i really don't want to exchange my phone, i don't have any of the other problems.
[HTC Sensation] cyrarchy:
what sort of battery times are acceptable for this phone? many are suggesting factory resets and all i wonder if i should do it or not. if i charge the phone overnight it goes to power saver mode usually say 8-9pm and then the power saver mode (basically dim screen and no gps wifi remains on) is managing to hold the power till i go to bed and charge it. is this ok?

juice defender seems to be recommended eh? maybe one should should try that before the factory reset. btw if factory reset done whats the best way to restore your phones contacts to how they are now? i mean it took forever to link all the facebook, phone and microsoft exchange contacts and offcourse gmails. dont want to go through that again.
[HTC Sensation] silentsnow31802:
I tried juice defender last night and it didnt seem to help. I lost 45% overnight without me even using the phone! When I fell asleep the battery meter said 100% still and I woke up to 55%. The phone says there is some awake time, wonder what it could be? As much as I dont want to do it I think a factory restore may be an option since nothing else is really helping. Should I wait until the battery is 100% before I reset it?

Some new pics, keep in mind I was asleep for all of this use except for what the screen awake time says.

I would say you battery life isnt that bad, if it lasts a day then it sounds about right. People are saying the batteries last longer after a couple weeks or so. If you do factory reset try and connect to wifi when google is restoring your contacts and such, it makes things go a lot faster.
[HTC Sensation] GuestK00431:
I managed just over 9 hours on my first charged but I'm recharging it now and it went straight up to 31% when it booted up again :S
[HTC Sensation] RoosterX:
Me and my gf both have a Sensation now(i upgraded from HTC Desire, and she a HTC Legend), we are both pleased with the battery on the phones, she uses stock Sense, and i use LauncherPro, though we did learn something from our older phones, the thing that drains battery extremely much is all the notification emails Facebook automatically send(gmail push), these are almost turned off to 100%, next thing is to turn off all syncronisation in the phone you don't use, ex. i use Launcherpro therefore i don't need the phone to update Sense's own weather, and so on.

We both normally charge the phone every night, but i guess my phone would last almost 2 days on days i don't use it that much.

I must say i am extremely satisfied with my phone, the thing that i dislike the most is the camera, or to say it in a different way, if i didn't know the SG2 had a slightly better camera i may have been more satisfied ;)
[HTC Sensation] karnovaran:
You should not have anywhere near 100% awake time unless you're using the phone at all times. You have some app that is not shutting down or auto-updating far too often. That's your culprit - find it and your battery life will improve.
[HTC Sensation] Wonderstruck80:
What app is this???
[HTC Sensation] phoenx06:
Its Battery Usage, in Settings, About Phone
[HTC Sensation] gotzta:
So...I left my phone on the charger overnight (about 8 hours or more) after I had depleted it to about 10%. Woke up, still charging, only had 45% battery! Wtf? And the phone was heated to about 50C. Not normal right? According to my battery info my screen uses 86% with a static wallpaper.
[HTC Sensation] PG101:
I would do a factory reset.. this is definitely not normal.. and if it still doesnt fix it, then go in for a replacement.

Got my Sensation yesterday.. played the whole evening (say about 3 hours) on the battery level it came out of the box.. then charged it in switched off mode for 8 hours (first charge).. now its on, on stand by, seems to be using less than 2% an hour...

Still early to conclude.. but i will be back later on to give you more details..
[HTC Sensation] gotzta:
It took a while to charge the first couple days as well and this charge I'm talking about was after a factory reset to fix another issue (video taken with camera not playing). I should probably just take it in and return it...
[HTC Sensation] PG101:
Update on battery

Minimum use (mostly standby) - Wifi on... for the last 2.5 hours I have lost 2%

THAT IS NOT BAD!!!!!

Oh plus one full restart in this 2.5 hour (not fastboot - FULL)
[HTC Sensation] r3awak3n:
My battery is horrible too bit I remember my nexus being the same and it got better eventually. I also have noticed that auto brightness on the sensation sucks, its always at full brightness so I have just adjustedbit to always be at 50 and its doing a lot better
[HTC Sensation] ilovepiaggio:
Same with me, I just factory reset i see, if tonight same situation i will take to the shop
[HTC Sensation] silentsnow31802:
I am using a HTC cable that came with my old Nexus One and the wall charger from my MyTouch 4G and it seems to be working fine now.

BTW!!! I did a factory reset and my battery life is WAAYYYYYYYYYY better. I charged it to 100% before bed then unplugged it to see how much drain I got overnight. Woke up 8 hours later to 96% battery!!! Much better than waking up to 56%! I am happy now :D
[HTC Sensation] cyrarchy:
observations after 1 week of use.

1. yes, battery life does improve with time.

2. idle phone battery usage is very good.

3. app like juice defender beta does help indeed.

4. no factory reset done and only using stock cable to charge.

hope this helps.
[HTC Sensation] :
My battery life is terrible.. losing about 4% an hour without touching the phone and when I do use the phone its dead within 8 hours with minimal use. Starting to piss me off :) Need a solution.. Anyone?
[HTC Sensation] martinchavez90:
Same here I'm loosing like 7 % every hour w one gmail on sync and weather WiFi off ... That's pretty bad right
[HTC Sensation] :
Solved my problem.

I disabled HTC HUB and Facebook Sync and now the battery seems to be holding its charge. Been at 69% for the last hour and a half, was losing around 4/5% an hour without use. Try that see if it works for you also.
[HTC Sensation] ledmeister:
How do you disable HTC Hub?
[HTC Sensation] ridder215215:
Ummm.. this thread is almost 2 years old. I doubt you'd get a response from the guy above.

http://lmgtfy.com/?q=disable+htc+hub
[HTC Sensation] usedusername:
Greenifying power hungry apps might help. I've tried it and it helps.
[HTC Sensation] Sensation Freak:
In my opinion a kernel, which is very close to a stock one, has the beste battery life, but not the best performance. There is still no kernel, which has a good battery life + good performance (my opinion).

Best tip to save energy is to reduce the display brightness (eg disable automatic brightness...).

With this tips i got a battery life about 2 days (with 4,5 hours display on), with anker battery.

[Galaxy S I9000 General] nicyhl:
Greetings to fellows android users and contributers ,

I would like to seek advice on what is wrong with my phone while im playing some games for example : modern combat 2 HD

I managed to flash my galaxy SL from XXKB2-----> XXKB3 successfully without any problems and also swapped my internal and external memory to give the phone internal memory of 14.8GB in total .

Before I swapped the memory cards , I was playing modern combat 1 and it ran smoothly . but after I installed modern combat 2 , some scenes during the in-game gunfire would flicker like a spoiled TV .

Questions :

1) is it because of the extra large internal memory of 14GB CLASS 4?

2 ) is it because of some steps Im supposed to take before I play some high-end graphic games.

sorry if my questions sounded noobish.

thanks for any advice. :D
[Galaxy S I9000 General] sakindia123:
Even i face this problem.but even without swapping.
[Galaxy S I9000 General] nicyhl:
any solution to this problem?
[Galaxy S I9000 General] monalac:
It happened with me recently after the swap of 32gb memory card to internal memory with Asphalt 6.

Just delete the data file required by game and re-copy.

Solved this in my case.

(i had backup of data files of asphalt 6 so i coped back to memory card again n deleted old)
[Galaxy S I9000 General] ephraim:
I'm not sure about my answer but i think this is the problem..

External And Internal SD Cards have different Write and Read Speed.. Internal is faster because it is built in your device.. Because you swapped your internal and external the default for data storage therefore will be the external SD which has lower read and write capabilities compared to internal SD.. (This is just my opinion and i'm not sure weather it is correct or not.. If i'm wrong please correct me :D )
[Galaxy S I9000 General] sakindia123:
I.dont think.so bcoz.other games which r.larger in size.are.vorking correctly
[Galaxy S I9000 General] ephraim:
I see.. Maybe try downloading the game again will work :)
[Galaxy S I9000 General] nicyhl:
I tried recopying the game files back into my Pseudo-internal memory card ( aka : swapped external memory card )

FYI : My external is Kingston class 4 16 GB

I did it 3 times but the game still have this problem ( blurred spoiled scenes when enemies are shooting me ) , same happened with my other game .

I searched the site I downloaded a software : SD speed increase ( by Diego Stamigni ) but it didnt work ady.. I put the value on 2048kb. ( original was 128 kb )

Is there any other solutions? thanks for those who helped. :D appreciate it
[Galaxy S I9000 General] fooman123:
Does running the game with power attached to phone help?

If it does, try installing setCPU from the market and setting it to Performance when you are playing the game.
[Galaxy S I9000 General] sakindia123:
Setcpu wont work........and playing while charging makes the fone smokin hot
[Galaxy S I9000 General] fooman123:
-does it get smokin hot- is not the question - Does the issue still exist while power is attached?
[Galaxy S I9000 General] nicyhl:
Nope.. I tried playing it with the charger on but no use too.

can anyone propose a solution to this?
