Hi all,
I folowed both part 1 and part 2 to root and unlock nand on my evo. I loaded the freshevo 0.3 ROM and applied the 4g fix from flipz. Now, my Evo lasts about 5 hours in standby before the battery is dead.
My Evo used to last most of the day before I rooted it. Has anyone experienced similar issues?
Thanks,
Rayden1000
Did you flash the new radio?
Did you leave 4g on?
Gps?
Bluetooth?
What are your sync settings for social network, weather, news?
We need more info than my battery sucks.
Flashed the new radio.
4G is on - as before rooting.
Bluetooth, WiFi is off.
GPS is on - as before rooting.
Syncing is at 4 hour intervals.
Exchange is "as items arrive" - as before rooting.
I know that everyone complains about the battery on the EVO, but my phone is dead after just a few hours of non-usage.
My Up time and Awake time are almost the same, so I think something is preventing the phone from sleeping. An hour ago I went to some setting that listed which app is using what percentage of the battery. I can't remember where I went to check that now, and it wasn't the stock battery settings app. It said that HTC Sense is using 97%.
Thanks,
Rayden1000

Also you might have a bug with 4g where it is constantly connecting or trying to connect. See if the fix above works. If not try damagecontrols rom and see if its any better. Or you can try disabling 4g and see if there us a huge huge huge gain.
I do know that right now some of the custom roms have had 4g issues. I'm not in a 4g area so its hard for me to test.
Thanks Aridon,
I already checked out that thread, my phone is set to CDMA auto.
And yes, I did have the 4g bug when I unlocked NAND through method 2. I found the fix that flipz posted and that has fixed the 4g issue. I also flashed the freshevo 0.3 rom that has the 4g fix built in.
I will try flashing the 4g fix again right now, but does anyone have any other suggestions? It seems that battery performance decrease is a common issue after flashing custom ROM's.
Rayden1000
You should consider doing the steps in that thread regardless if what it shows. The hero had a display bug in that regard for some and perhaps so do some evo. Seems odd but there are differences because when you start playing with kernels it will boot on 002 devices but not others so there are differences.
I'd do it, set it and reboot. Don't go back in to see if it changed just start a new battery test And check for improvement
turn off 4g, my evo has everything yours does! but end of the day i get home and still have over 50% battery life left! if you have 4g on it drains the crap out of battery. only turn it on when your going to use it!

I do understand that 4g decreases the battery life significantly. What I am trying to say in this thread is that after I rooted and unlocked nand on my evo, the battery life is MUCH MUCH worse then before rooting. My phone's battery now goes from 100 to 0 in about 4 hours - while I am not using it at all.
I am just trying to figure out what process is running all the time and prevents the phone from going to sleep.

Dude download Overclock Widget. Do a google search for: Overclock Widget HTC Evo.
I swear on everything I love that after I installed it and went through the settings my battery lasted 11 hours today. I still had 23 percent left and I streamed some videos on the web, listened to music, played around all day with my phone. It really works and some people claim 30 plus hours of battery life.
It works and I will post a screenie tomorrow of the proof.
Whatever it was, installing Damagecontrol 3.1.2 ROM "appears" to have fixed the issue. My phone has been in standby for about an hour and I have 93% battery left. I will leave it alone for the night and will post the battery status tomorrow morning.
Thanks to everyone for trying to help.

I may have spoken prematurelly, this morning the battery is dead again. I have tried numerous ROMs with the same result. I also tried old radio ROM ans new radio ROM.
Has anyone been successful at following both part 1 and 2 of rooting and maintaining decent battery performance?

Not to sound noobish, but did you already disable GTalk auto sign in and then sign out?

Did you NOT just read my above post. I clearly gave you a fix SMH. Here's proof of what I'm talking about:
I took a screenshot with the ShootMe app. I'm currently running Fresh's latest ROM. The screenshot indicates that I had it off the charger for over 14 hours. I used my phone today to send a lot of text, skyfire, streaming flash websites, etc. By the way I have about 40-50% battery left.
Installed overclock widget, set it to run at around 247 mhz at all times - same result. Evo battery is dead after about 4-5 hours. Does anyone have the original ROM for the Evo? I tried running the RUUxxxxx.exe files, but they all fail - probably due to me rooting and unlocking nand, therefore modifying the file system.
Rayden1000
I've been running Fresh 0.3 for a few days now and haven't seen a problem. Have you tried getting a task manager and making sure there isn't a program running in the background causing all this? Also, is your phone hot... if it is, it means you go something taking up some major cpu time.
I had a similar issue with my Hero, the cause was it was trying to sync the calendar over and over non-stop. You should look at your account syncing also, there could be a problem there.
Sounds as if you have something running in the background that is killing your battery. When you are flashing your roms, are you doing a wipe first or just flashing over whatever you had before?
I don't see how you're running overclock widget and getting bad battery life. Download Advanced Task Killer and kill those tasks.
I also had an issue like that after installing some ROM (I forget now what one, since it was a while ago) and my battery died over night while I was sleeping. I don't really know how (if I did) fix it, but I wiped everything, factory/data/dalvik/battery stats (whatever that is) all those options, then installed a new ROM and it seemed to work fine.
As for the overclock widget, I downloaded that and tried to use it, but it didn't seem like it worked. It just didn't seem to stick and I didn't really see any increase (maybe even a decrease) in battery life. Probably the best thing that you could do is get a task killer and see if there is something running that needs to be killed. The awake time shouldn't be anywhere near the uptime
Hello all,
I've had my EVO for about 2 months so far. I've notice just like everybody that the battery life sucks to hades. I've rooted the phone since then.
1st problem) Maybe it's me or it's a problem no one addressed yet, The phone will start getting hot when it is in standby mode. When the back light goes out it gets hot. I've check to see if there were any wild or un-needed services running and there isn't, and its not like McDonald's Coffee hot but very very warm to the touch. And when it does that the battery life starts at 100% and ends at 20% within 40 minutes.
2nd problem) I've installed two programs in which I've deleted since the time it happen. A Super User Permission app, the one that's gray and has the jolly roger look to it. The next one is Juice Defender. I notice the problem after I installed them that the phone will start restarting itself like every 3 or 5 minutes. I'll be in the middle of a phone call and it would go blank and restart. The only time I notice it doesn't do it is when I connect it to the computer while I have debug on and when I do a hard restart in which I pulled the battery out. The battery trick only lasts for about half a day. I installed those apps 4 days ago, both at the same time.
My phone info is:
Software #
1.32.651.1
Firmware version:
2.1-update1
please help!!!! it's driving me up the wall.
I'm no expert but it sounds like a rogue app to me. If my phone were doing that i would wipe it and start from scratch.
Just my thoughts.......

Try updating to one of the rooted 2.2 Froyo ROMs. Be sure to do a full wipe (data, cahe, dalvik-cache) before installing a new ROM, unless otherwise instructed. You're running an old software version of Eclair (current Froyo is 3.26.651.6). I've received considerably better battery life since the update to Froyo, especially with a custom ROM and custom kernel. I personally run both SetCPU and Juice Defender with no problems or any overheating issues.
Mostly it sounds like you have something locking your CPU usage at 100% which would explain the heat and battery drain. I suspect you may be having software conflicts using the old OS version. Do a Nandroid backup before flashing a different ROM so that you can rollback to your exact setup you currently have if you do not like the results of the updated ROMs.
And by all means, DO NOT flash an unrooted stock Froyo ROM (or take any OTA update). There still is no method to root that.
Yeah I have been debating the whole wipe the phone and start with the 2.2 OTA and wait till they root that. This is driving me mad, cause it's seems it knows when I need it the most. When I'm at the house it last and stay up like a champ, when I leave it starts acting up.
Which leaves me with the question how do you save the apps on your phone?

Appbrain is a good way to manage apps. Any paid apps should still show up in your downloads section of the market after a hare reset. I have no battery problems with the ota 2.2 patiently waiting root. Don't know if I'll root when they do figure it out because its pretty stable with decent battery life for me.

So today is Day Two since I changed the ROM. I have notice alot has changed, some things are new, and some things are working that never work before. It's like having a new phone all over again. LOL
I also use the instructions in the thread about battery life
Edit: I can't link it due to new user access. But its in the General fourm.
15 hours and I haven't plugged it up yet to recharge it yet I still have 60% left on the battery. I made 8 phones calls that lasted 2 mins and more, plus ran the music app and more.
I want to thank you guys for your help
Do you getting more then24 hours on a stock battery?
Do you keep 3g on and always connected checked?
You have to be a real light user
No sir.... by no means I'm I a light user. As I stated I use my phone pretty heavy and that was only day two that I done that.
Yes....I now get more then 24 hours out of the stock battery.
At 7am I unplug and jet out to work. I use my phone as a MP3 player for the car. 30 minute drive to and from. When at work I play games and make random phone calls for 9 hours of the day. SN: I'm doing my job also When I leave work I go to my gf's house which has no signal out there. I use to have to put it on Airplane Mode to save the battery. Now I just leave as is without changing it.
Total time using the phone in 24 hours: 14 hours
Times I charged my phone in 24 hours: 0
Battery Percent in 24 hours after 14 hours of use: 45%
Longest hours since unplugged: 2d 2h 4m 10s with a 50% life left.
Yes I keep my 3G on. I turn my GPS off and Background Data, Set the weather app or widget to update every 6 hours (Why would you need to know the weather every hour on the hour, Just press update when you open the weather app) along with other things I don't need running while I'm at work or even not using them.
This is with the OMJ Froyo 2.2 Rom update. The phone is still running smooth and as it should (in my opinion)
One minor but major problem to some I wish they would fix.
Multi-touch though out the whole phone. The Droid X, Incredible, and Nexus 1 has it.
Why can't we have it. I would be so happy if we can get that.
I got a heavy battery drain after flashing to the official Kies 2.2 here in Norway, on JM2 I had over two days usable time, now down to a normal day.
I've reset it several times, tried running it without any apps at all, still heavy battery drain. After checking the battery statistics/history I can see under "Partial awake time", Android System, 2 hours after 14 hours "uptime". And under "Sensor use", Gallery eats up 9 hours, 11 mins. Now what the hell is that about T_T
At least waiting for the new official fw in november.. At least the GPS got better for my part, so it's not all bad
After updating to the official 2.2 that came here in Norway, I started experiencing heavy battery drain compared to before.
After some digging I noticed under *#*#4636#*#* and Battery History and Sensor Usage, Gallery is on top! And it's using the phone's sensors almost 100% of the time it's been on. So, now; the phone has been unplugged for 12 hours, 14 minutes, and Gallery has used the sensors for 12 hours, 4 minutes. Doesn't make sense.
I suspected wifi to be the culprit to begin with, as it throned at the top in the normal battery drainage-graph (about phone, battery usage), but even if I turned off wifi, 3g and autosync over the night, the battery percentage fell just as quickly.
Now, I've tried resetting the phone several times, as I thought it was an installed app that caused the drainage, but that wasn't the case. So, what else can I do when a reset doesn't do it?
Using a GT-i9000 with JPM/JP6 non-rooted.

Well, for what it's worth I too experienced exceptionally high battery usage when I updated to JP6 via KIES hack (same version as yours). Downgraded to the latest stock ROM for my region (Eclair JG4) and the issue is gone.
Now I think I will wait for the official 2.2 update for my region (although, having had a peek at what Froyo has to offer I think I can pretty safely even skip it without missing much).
I too notice a lot of power drain and general lack of ram. What I found was that froyo has a crapload of startup services/processes compared to eclair. I disabled most of them that could be removed and replaced most of the rest like k9 for email and handscent for messeging. System seems less laggy due to more free ram and more power as CPU isn't bogged down by extra unwanted processes like samsungs remote wipe and stupid sns

I'm also suffering from battery drainage with Froyo (JP6). I was quite satisfied with battery use on Eclair. Froyo has reduced battery life almost by 50 percent. I have same programs and I'm using exactly the same settings than with Eclair. I haven't noticed anything odd from the battery history statistics though. Only strange thing is that phone reports that screen in consuming over 90 percent of the battery all the time. Well, that's just not true.

it's a sensor issue, looking at the spare parts batt usage stats. but no idea what sensor/app is the culprit. very annoying
An App I use daily for all manor including checking battery usage is 'SystemPanel'. It's been a God-send and sorted out many a problem.
There's a Free & paid version but the App is that good I immediately went for the paid App.
In 6 hours battery has gone from full charge to 85% in standby mode.
Is this normal? Charge goes awfuly quick when using the phone.
3G on, all syncs off.
Running on Froyo reg hack. Same problem on Eclair!
Phone is 85% charge from full charge on idle over 6 hours.
3G is on, 2 bars showing. WiFi on, not connected.
Display 50%, WiFi 30%, Cell 14%, Phone 6%
Froyo, Eclair same usage except Wifi connected better with Eclair on home network...
2 meters from wifi transmitter and signal fluctuates.
Also, anyone's stock browser lags with yogurt? Was good on eclair
Is it because of fash? Seems to lag on all sites now.
Just to add to this... I had similar battery life in Froyo... HOWEVER, yesterday I used the Gallery and my battery drained from full in under 10 hours with no use (overnight standby with data off).
I check my battery stats when i switched my phone back on and they're okay for the 'since last unplugged'... however... for 'all time' gallery is also my highest user!
So, looks like gallery is only a problem if you use it... if not, it's fine.
crabby
I also have like a 2hr sensor usage on my gallery...
About the light sensor atleast on the JPM/JP6 theres like 2 steps of brightness full and low.. is this normal ?

Sensor usage for me was also 100% in spare parts, even if the phone was off. I had to turn off auto-rotate, and it quickly became a lot less. Although I have to say it haven't solved my problem! My battery consumption with full brightness over wifi is 10%/30 min. That's just ridiculous. I'm still on the problem, and will update anything I find out. We could actually make a "BIG BATTERY DRAINAGE" thread, where everybody posts detailed logs about the drain.

just a question. you guys that are experiencing the sensor issues, are you on jp6? could it be a jp6 issue?
Exchange email accounts are a huge drain to in Scandinavian Froyo
If you set up Exchange email accounts, setting the Email retrieval update interval to anything else than 'Never' results in a continious 10% CPU load, draining the battery two times faster than in Eclair 2.1
Set it to 'Never', or have Tasker kill the Email app x seconds after Display Off
Determined by using System Panel app.
I have notice a large battery drain overnight with the OFFICIAL samsung froyo JPO. I suspect it may be the gallery/sensor issue.
1 can anyone affirm this.
2 can we replace the gallery or fix it

JPA was better for me. With JPO I noticed that the media scanner would eat up the CPU all the time. It seems to get stuck on certain files more easily.
Hello Everyone!
I made this thread hoping I can shed some light to those getting very poor battery life. I was also getting very poor battery life, till I went and exchanged my phone for a new one. If you're getting very poor battery life (even after wiping your phone or installing a clean firmware), there is definitely something wrong with your phone or your battery.
I own a i9000m bought from Wireless Wave. I've unlocked the phone and am now using it on Rogers.
My previous phone, I was draining 25% of my battery to just get through 6 hours of standby while I slept. I had juice defender on and autokiller memory optimizer. I turned off all syncing and didn't even use a live wallpaper. My phone was rooted and also had lagfix (which I soon removed). One thing I do remember doing is not charging to 100% when I first got the phone. I did accidentally let it drain to 0% cause I had to use it right away.
After exchanging for a new phone and charging it to 100% right away, I was getting the following results. I have juice defender and nothing else. I changed my band to be WCDMA only. I even have a live wallpaper on. Last night my phone idled for 9 hours and it only drained 2%! Last night going out, I had a moderate to heavy (fbook, 3g, gps, text, youtube) usage pattern on my phone and it only drained 40% after 6 hours of use.
I don't know what else to say, but I'm letting those with battery problems know that the SGS is capable of great battery life. And if all your optimizing and tweaks aren't doing it, then you may want to consider exchanging for a new phone if you still have warranty.
I have a great battery life too in my device compared too the another smartphone i used in the past and now compared to Ip4 and N8 in this devices the bat drain is much higher. So im positive surprised with
the galaxy battery performance, i only use the push email everything else is turned off, livewallpaper and so on..

My phone came with JM7 firmware. My battery life is just excellent, not needing a recharge before a few days with my use
Running JPM here, with darkyy's raw metal ROM, my battery life went up by at least 40% - %50. I was losing 1% per 5 - 10minutes of usage, now its more upwards of half an hour of usage.
I think the phone has very good battery life if you understand what can cause battery drain and adjust it accordingly.
I am now gettining 5% drain per 24 hours on (almost) standby. This would give me about 20 days of standby which is crazy.
Here is my setup:
UK 16 Gb Galaxy S with Eclair JM6 and Voodoo lagfix
Set network to GSM (2g)
Disable internet usage (with APNDroid)
Disable WIFI, Sync Off, GPS Off (with power widgets)
Just before I go to bed, I run Advanced Task Killer and kill anything that doesn't need to be on memory (inlcuding Advanced Task Killer itself).
Using your phone WILL spend a lot of battery. Browsing the internet on 3g is a battery killer. This means that if you do something on your phone that maintains an active 3g connection, it WILL drain your battery in about 3-6 depending on your 3g coverage.
WIFI is better, but again you are looking at something between 6-12 hours of continuous usage, so make sure you only use it when you need it.
Finally, if you need to have your emails the instance they arrive, go for a blackberry because it has the only way of pushing email without maintaining a constant data connection.
I don't need this so I am extremely happy with my phone and the battery life I can get out of it.
I hope this helps.
Have my phone set for 2G with wifi always on.
Use wifi at home.
2G is enough for all normal syncs, and if I need more speed for anything else I temporarily switch to 3G for that.
This way a single charge last me well over 24h under normal usage. Don't even know exactly how much.
With the phone set to 3G, the same usage patern will eat a full charge in something like 8h.

JPM Rom with everything except bluetooth turned on my battery lasted 3 days with low usage (skype a few times and some phone calls and a bit of wifi web-browsing.)
Much better than my wife's iPhone 4... Normally charge it every 2 days.
I am very happy with the phone, just a couple of bug fixes and I would really like it if Swype did some level of contextual checking of words to help minimise unnecessary corrections (perhaps they do already, but it is certainly not well implemented/sophisticated enough).

Eclair for both. No Froyo.
what i wish to have is greater control over the phone, more easily.
Some kind of powertop GUI that let you see the power usage per process.
So you could plain uninstall apps installing ****ty services consuming the battery.
Likewise i'd like *real* control over which background services are running. I mean running an auto killer wtf? Horrible design!
I just want to switch off a service and that it doesnt start again 5 min later thank you very much.
Even the task manager is quite bad. You see last started apps but you don't know which one is running right now. And if its running and backgrounded since a while and you started other apps.. it might very well not even show up in the list anymore. Horrible design again.
Saying all that because stock the phone battery is excellent, installing a couple of popular apps kills it..

Sure thing. And thanks. KIES offered an update from JM1 baseband and JM2 build version. We'll see how the new ROM performs in about 3 days. Unfortunately don't have spare time to do that sooner. I suspect there's huge difference within the baseband versions.
hey guys.
i have galaxy s i9000..i also had problem of battery.my battery would hardly last 24hrs...i even switched to gsm only mode n switched off sync.but still had same prob..few days back i installed JPJPA firmware..now its wroking fine.lasts more than 35hrs...n also battery charges quickly
Is it possible that the reading on the phone is wrong? When you say you are getting 24 hours are you letting it run flat.
Alternately is it saying the battery is running low and you recharge before it goes flat?
Just wondering if the meter is simply giving incorrect information.
Been 24 hours since last recharge. Lost 6% so far. Running JP6 Froyo. Rooted. Network Data Off. During this 24 hours, just used Angry birds-30mins and ColorDict 5mins. Haven't installed any unnecessary app.
Had lost 1% on standby after 14hrs with no usage. Thats amazing. Very Happy user.
Also want to tell u guys that GPS with active Data connection and Google Maps running and display on took approx 1% of battery every 3mins.
Impossible using stock battery, this phone draws a minimum of 10% battery per hour the screen is on. Its more likely 15-20% with most peoples phone.
Your battery meter may be inaccurate, for example after flashing once my battery stayed at 100% for hours then suddenly shot down to 20%

I use "Battery Indicator" to check my battery status.
My screen is set to turn off and lock after 30 seconds of idling. So it is quite possible to achieve the standby times listed.
Hi, how long do you have holding time of battery, when you are using wi-fi? (browsing)
Hey guys i just recently installed American Android rom onto my HTC hd2 And while i love android and it works almost 100% flawlessly My battery life has suffered alot.. with windows running i can get over a day of use on standby. With android running i get around 12 hours if im lucky. if i make calls and use it it drops to around 5-7 hours. I have juice defender installed wifi bluetooth and gps off. I cant think of anything else that could be causing it the only other thing if it even matters if My 3g coverage goes on and off all day but idk if that would cause the battery to drain.

Hey guys i just recently installed American Android rom onto my HTC hd2 And while i love android and it works almost 100% flawlessly My battery life has suffered alot.. with windows running i can get over a day of use on standby. With android running i get around 12 hours if im lucky. if i make calls and use it it drops to around 5-7 hours. I have juice defender installed wifi bluetooth and gps off. I cant think of anything else that could be causing it the only other thing if it even matters if My 3g coverage goes on and off all day but idk if that would cause the battery to drain. Any help or tips on the issue would be greatly appreciated.

You could easily have used the search button and not have had to create a post like this :/
Refer to this video for more info about that.
Download CurrentWidget and check your battery drain on standby, it should be around 4mA. With screen on, there isn't much you can do really other than to lower the brightness etc.
my stats
i downloaded current widget but im pretty new to this so the stats when im on the home screen are 152ma 3.762 V it randomly spikes to 550 then back down to 150. idk how to check the screen MA itself ... My Android system is 30% , cell standby 24% , phone idol 17% , voice calls 15% display 10% mediaserver 3% music 3%.

150 is decent for screen on (at least it is for me, may be crap for others) and to check with the screen off just turn the refresh interval to something like 10 seconds, wait a minute or so to let it settle then unlock the screen and look immediately at the battery drain. If this is higher than 10mA (at the very most) it isn't good at all. Try with airplane mode on as well, would lower the battery drain significantly.
