Battery Life

Hey guys.
I've been wondering.
Lately im using my TP2 (unbranded) quite a lot and my battery dies out fast. Everyone is saying that if your battery life sucks you should try to switch radioflashes.
What is your general battery life, what rom do you use, what radio do you use and how much do you use your phone?
Im using the GTX themed EnergyRom LEO 23-build (apr-8)
Radio: 4.49.25.17
I use it quite a lot and if im lucky i squeeze 2 days out of a full charge.
Keep up the good work guys!

2 days is good battery life

Is it really that bad ?XD

2 days is amazing. With my screen off most of the day I can get 36-48 hours. If i'm on my phone all day and the screen is on I'll get around 24 hours.
And what are you talking about? Most phones I see are lucky if they get to the second day on a full charge.

Yes, actually anything over a full day's use is generally "above average" for this phone.
The best ways you can make sure you get the most out of your battery is to switch off 3G/bluetooth/wifi at any time that you're not using them, and to not leave the screen on any more than necessary (unless it's connected and charging). When I keep those things turned off most of the time, I can easily get up to 2 days (or very close to it) out of the battery...but as soon as I start using any of those more than lightly, a full day of battery is all I count on.
If you do have to use any of those regularly, then flashing a different radio might help...sometimes you'll get more efficient use of the 3G/bluetooth/wifi with a different radio, but trial and experimentation is the only way to know if another one is better for you or not.

Yes, any type of data connection uses up battery much faster, due to the fact it has to broadcast data over the air.
Unless you've specifically turned off 3G permanently, mail, weather and twitter will all switch the 3g connection back on for what they need, and will leave it on (draining your battery) until you manually switch it off again...

[Q] juice defender

Aight so I downloaded juice defender free last night cause I've been having battery heat problems.....but it shuts off my 3g connection when the screen goes off and I can't seem to find the setting for it....I use Pandora radio so this is a bit of a *****.....any solutions?
Sent from my Incredible using XDA App

Thats pretty much the only thing Juice Defender free does that can save your battery, that and turning off wifi too. So if you disable it why even have Juice Defender installed? I too tried the free version for about 2 days and could never get my wifi or 3g to come back on so I uninstalled it and thanked god I hadn't paid $10 for the paid version. IMO its crap.

Juice defender is terrible. It kills your battery. well thats my experience...

Terrible app. If it does anything then it kills the battery... Brings android system to the top of the usage list, because it shuts off 3g and wifi..
Sent from my ADR6300 using XDA Premium App

Screen is still the top on my usage.
I have the paid version. It gives you the ability to lock items (like Pandora) "on" for data usage. Then, they don't get killed.
I had amazing battery life with it on my D1. Jury is still out on the Incredible. I'm still working through ROMs and Kernels.

I use it also. It has this new feature that you can tell it your local wireless and leave it alone. Problem is it doesn't work. Keeps shutting off my wireless when I'm using it! Very frustrating.
Also their developer is not very accessible. They want all issues solved through their forums. I hate that...The best software also has an accessible support system.
The one good thing I will say about it is it has the potential for taking over all aspects of managing your phone. A one stop shop. Just not there yet...

I used to use Juice Defender with 2.1 and found that it helped battery life. However, with Froyo, it just made the phone unstable. (It'd just sponaneously reboot sitting on my hip 2-3 times a day.) After uninstalling all is well.
A co-orker's Sprint phone had the same flakyness until he uninstalled JD.

Wild! I have never had random reboots. But, we all know how unique these devices are... even between the same model.
With warm twopointtwo, it doesn't seem to be turning on all the time... or warm is somehow killing it.
dbaps - are you still in 'training' for the wifi? It takes JD a couple of times to fully learn your location (based off of towers) and remember that as a wifi location. Check under the settings...it'll tell you what percentage of training it has completed.

Those of you who say its crap obviously dont have it configured correctly. I bought "ultimate juice" and when you go into the custom or aggressive profiles you can tweak everything until your heart's content! It still seems to shut off data when Im streaming stuff with slacker and connected to wifi, even though I tell it not to. Other than that it definitely will give you a few extra hours if you spend the time to configure it properly.

Terrible app!

There is no correct configuration to this app. That is why it is called "Custom". The reason it is CRAP is due to the reason you list as a problem among numerous other features that don't work.
Seriously, why have an option to automatically tweak CPU values if the option doesn't work with 99% of the kernels on the market, which also includes the STOCK kernel?
Yeah, it's a GREAT app!

True. For clarity's sake, I was using JD free so I don't know if any other version would have been better or worse. It's possible that the complex WiFi network at work (multiple APs per floor with a centralized controller) confused things.
My phone is a droid incredible, the co-worker's is a Sprint Epic. Different symptoms - he had phone lockups requiring battery removal to recover. Rooted, re-ROMed and still crashing until Juice Defender removed.

If you use Ultimate Juice and set up things correctly. This programs rocks.
It will turn on and off your data (3g and wifi) when you need it (according to the conditions you set).
It takes a little bit of reading and intuition, trial and error, and PATIENCE.
Use it for more than 1 day. Your phone usage varies day to day.
Again, read the text, THINK, and setup the conditions according to the way YOU need them.
I get at least 20-40% more battery depending on how I use my phone. I rarely charge mid-day any more and I can count on my phone having battery throughout the most useful hours of the day.
On light to moderate use, I get at least 14-18 hours. Just for fun, I once tested it and got about 29 hours before the battery hit 5%. That's with a little texting and a few phone calls. I use the stock, standard capacity battery as well.
SET IT UP RIGHT!

I've had no issues with JD running on 2.2.
Set on Aggressive. Only annoying thing is that I get the error notification icon for Weatherbug Elite every two hours because data is shut off.

First - I've got the most recent JD installed. The old one was kind of lame. People have made some good points, but there is a lot of incorrect information in this thread...
It works. If you are *NOT* actively using your phone, it will save your battery by disabling communication you don't need. I can go to bed at 80%, wake up 7 hours later at 79%, maybe 78% at the worst case.
If you are using your phone, it's quite nice - it comes on quickly - and manages my network well (at home, uses WiFi, elsewhere - 3G).
It's not $10.
My wife is using the free version and has had zero problems.
I've never tried aggressive, but maybe I will.
I cant comment on the CPU stuff - never used that.

I've never had a problem either. I'm running Skyraider 3.5 with incredikernal 2.6.32.27. I have the free version set on advanced. The best battery lift I've gotten with light phone use, texting, data syncing and browsing was 72 hours. Same use with stock rom and kernal my best was about 18 hours before I needed to charge. I know everyone is different, but that's my experience.

When I tried it back last Fall the paid version was indeed $10, its now down to $5. Which I still believe is way too much for this app. My 3g would not turn back on no mater what I did and yes I read the tutorials many times and had it set properly.

Perhaps for you. For me (stock ROM on my dinc) it made the phone unusable. Calling that observation "crap" or "lame" is convenient, but doesn't reflect the experience that I had (and which others had).
Again, with Android 2.1 JD did help a great deal. With 2.2, it didn't help battery life but made the phone crash. This was not a positive trade-off.
With froyo, I can go two days on my incredible between charges given light usage without it. Why put up with the instability just to get a few extra hours of battery life?
For example, I'm currently at 62% after 15 hours since unplugged with moderate usage of the phone, with WiFi and Bluetooth enabled. I could just turn off Bluetooth except when I'm in the car, but I doubt it'd buy me more than a few extra hours of useful life.

Juice defender has caused me multiple problems. Was the source of phantom call drops and sleep of death!! As soon ad I removed it, problems solved.

Also corrupted two SD cards, losing all my files, because of sleeps and reboot caused by JD. Does not play well with Z and HD roms at all. Works at first but soon became the cause of a lot of problems.

2g/3g/4G Juice defender beta

Anyone use this from the market?
I wanna test out the 2g/3g/4G mode but it's giving me a warning that it could break my data and not able to be restored so I'm too chicken **** to test it.
Sent from my Galaxy Nexus using XDA App

Yes. Swear by it.
There are plenty of nay-sayers, and no doubt you'll hear from them here. I wouldn't argue the experience they've had, but then, I don't see why they argue mine (and other happy users).
I had terrible problems with battery drain on my Epic 4G. I had a lot of crap running, keeping the radios alive all the time with little junk that was just fine updating in bursts every 15 min. when JD wakes up the cell radio for apps to do some traffic.I'm also not OCD enough to remember to turn my wifi on and off.
Anyway, with JD and my configuration, I sip electrons. Take JD away and... not so much.
Put it on the GN and it seems to be working just as well if not better. I see threads full of people complaining about battery life -- I'm easily getting a day and a half out of mine with moderate use (maybe 20-30 min total talk time, some internet, YouTube, 20 minutes of gaming, and other typical usage). Sitting on standby, I lose about 1% and hour.
When configured properly, I find JD helps a lot, chiefly by automatically managing the radios. Worth it.

But do you specifically use the 2g/3g/4G toggle or do you just have your profile set to turn data off?

Yeah, sorry I wasn't more helpful about that. I only answered your first question
I don't use the specific toggles. I just turn data entirely on and off. I didn't see the benefit of switching specific data modes.
Yes, 3G uses less power than 4G, and 2G less than 3G, but OFF uses the least!

Haha np, I just like to be able to get my emails and mms etc.. At all times.. But hate leaving 4G on..
Just thought it would be perfect to have a profile to turn it to 3g or 2g like 30 seconds after the screen goes off..

Juice Defender is, without a doubt, the worst app I've ever paid for.

I had problems with JD on my SGS but it seems to be working much better on the GN. Stops the battery from draining while I'm not using the device. The main thing I'm using it for is controlling WiFi by location. I only have a few apps enabled with the screen off so it shouldn't be using a lot of data.

JD worked great on my SGS2 and works same way on GN - thanks to JD I loose just 2-3% over night.
I don't know if it's bad configuration or ROM incompatibility for the people that complain about JD.
Anyway, I have seen that 2G/3G/4G option but didn't have time to look around after beta version, anybody care to share a link? I would like to see if 2G is good enough to keep my internet radio going, it's currently killing my battery, like 10-20% per hour. Is there an option to use 3G, but no HSDPA?
When idling, with properly setup JD schedules and triggers and auto-brightness also managed by JD, I get great battery life.

I may as well weigh in with my view on this, as an agreement with both sides. When I had JD Ultimate loaded on both stock and custom ROMs on my Gnex, I undoubtedly saw battery life gains when the phone was idling, and they were significant. However, far too often I would go to unlock the phone, and the touch screen would be unresponsive and I would have to battery pull. Not once has this happened without JD running. A couple of times a day with. So it worked for me, but the instability that came with it was too much to bear, so I uninstalled.

Yea I know it's possible, but I just like that JD manages so many things for me, like auto-brightness, radio schedule or that it automatically enables WiFi when I get home and disables it when I leave and can do the same with Bluetooth if I wanted.
Surely I will uninstall JD when I loose interest in its advantages or when I find a different app that works better for me or when I simply get bored with it.
I only had to pull battery once since I installed it, which is not that bad. If it starts to annoy me, I will get rid of it. But so far it's ok.

My issue is that I don't want something controlling my phone. Too much control. I can all those things myself if need be. Isn't that the whole purpose of Android phones? To have control?

For me, the solution is to use JD to let it manage some boring things for me so I can focus on other more interesting stuff.

This.
Except never had a crash or lockup, never had to pull battery.
I'm a flash maniac, hacker, and mod extensively. I run a lot of crap on my phone. JD does a great job managing things automatically so I get great battery life.
That is, JD ultimate... the free version is way too limited.
Only problem I've ever had is JD bring really slow to turn data on when I wake up the phone, after its been running fora long time (like into the second day). Fixed by stopping and restarting JD most of the time.
Rarely happens because I reboot at least once a day for one reason or another.
Arguing over whether JD is "great" or "crap" is so juvenile. The fact is it world great for some, not for others. This speaks to configuration differences, not JD. Is Supercurio's voodoo sound crap because it doesn't work on some configurations? Of course not.

To offer a different perspective, I don't consider something for which I control the parameters to be "not under my control". I'm not seeing how JD's behavior is any different than the phone automatically connecting to a wifi AP if you leave you're wifi on without you explicitly telling it to connect.
If JD simply enabled some vague power savings through turning the radios on and off, without knowing exactly what triggers the control, I'd stay far away from it too.
Sure, its turning radios on and off, etc. -- exactly as I've instructed it to. I'm in complete control.

Battery drains extremely fast because of mobile data

Hi My Friends ,
when I use mobile data networking ( GSM & HSPA ) it drains so fast , cant i just go for edge , there is function for it in iphone , you can turn off or on 3g , is there any function in nexus ?
Because it drains so fast , it drains one percentile per a min , it means that battery drains in 2 hours
Google are you kidding us ?

Its not the data. Its probably what you're doing all together. Actively using data means that 1) the screen is on, which is the biggest drain and 2) the processor is actively running, which is the 2nd biggest drain.
If you want to switch to EDGE only, go to Settings > More... > Mobile networks > "Use only 2G networks"
You'll still get about the same battery drain because the screen will still be on, and the processor will still be working. Any savings you get from slower data will probably be wasted by keeping the screen on longer to complete the task.
I'm assuming you just got the phone? Use it regularly for a few days and stop watching your battery % and you'll be fine. Checking your battery just drains more battery...

Believe me i have been doing nothing , and it drains so much fast compared to HTC Sensation , my gf has a htc sensation and it also use 4g and we dont use it , and the result is HTC drains 2 % and mine ( galaxy nexus ) drains 17 % , we dont have any app under working , believe me this phone is the worst second thing ive ever had ( first one is Iphone 4s )

Why so resigned? maybe you have an app not playing nice and/or draining more on ICS than in a previous phone. I use my phone for heavy use and sometimes drop about 10-15% in an hour.

uninstall all your apps.
check all settings of apps still on the phone.
and see if the battery is better.
often its an app that is using a lot of CPU or Data in the background causing it to never really sleep.
Maybe use CPUSpy to see if its the cpu which is causing the drain.

Looks like you might want to go back to the drawing board and spend another 2 years trying to learn Android. Surely with your vast knowledge of smartphones and computers you would have figured out the problem by now. Hint: It's you. Damn, well I gave you the answer.
In all seriousness, you are the reason for the problem. You control the apps installed. You control the permissions these apps are allowed to have. It is your job to monitor activity and make sure none are misbehaving. Don't blame Samsung, Google, or anyone else.

Antennas
Wifi
Consumes more energy per time when trasmitting than mobile data, BUT...
Takes less time to transmit data, espescially large files, so it consumes overall less energy.
Wifi scans for a connection and pings the router less often than mobile data, thus consuming less energy at idle
Bluetooth
Consumes a small amount of power at idle to connect to new devices
Scanning for deveices consumes more energy
While connected, very little energy is consumed unless data is transmitted.
GPS
Unless an application specifically invokes the GPS antenna, it will not consume power
Using constant GPS updates (as in Navigation apps) will consume a large amount of power
Some apps will have bugs in them which will keep GPS on indefinitely. Try reinstalling those applications first, then remove if necessary.
Mobile Data
2G antennas consume the LEAST amount of energy at idle, but because they take so long to trasmit data, they can kill your battery.
3G antennas are Ok at idle, but take less time to transmit data, so are the best all around for traveling around metropilitan areas.
4G Antennas are FAST, but consume the most power. Best to leave these off when in transit, and used for stationary, stable connections
All Antennas consume much more power idling in areas of bad reception. So if you know you're going somewhere with poor reception, and don't need data, turn it off until needed (Settings->Wireless&Networks ->More ->Mobile Networks-> "Data Enabled"; "Data Roming" OFF; "Use Only 2G Networks"

Because it drains so fast , it drains one percentile per a min , it means that battery drains in 2 hours
Google are you kidding us ?

I never turn off Wifi, H+, 3G or GPS. Sometimes I forget to turn off Bluetooth after I get out of my car and just leave it on for the heck of it, that while a blue LED is blinking on all the time to notify me Bluetooth is on. It would still last me the 6-8 hours i'm away from home with regular usage of browsing, checking mail, messaging and stuff until I get back, and even then it would still have some power in it. Lasting only two hours means something is wrong and I doubt it's the data networking. Check background services and widgets refresh intervals.

Wasn't trolling, only saying that I think that the data connection is draining battery as I'm getting 6hrs screen time browsing with 50% brightness against 2-2.5hours of data browsing with 25% brightness. So, I think there IS a problem other than the screen that maybe someone has the answer to...

Recommend A Rom? Need To Save Battery

Hi,
I just got my HTC One X and I love it. The only downside to it so far is after leaving it on charge overnight im lucky if I get 5-6hrs out of it.
Im on the default OS and ive only installed some apps but im pretty much in the dark where to start.
Can anyone recommend the best rom to use or even just good apps or ways to make my battery life extend?
Thanks and again sorry if this is a noob question.

Have you updated your device with all the official updates? Have you disabled fast-boot, auto-brightness, satellite-GPS and all other wireless options that you don't need and opted for a 30-40% luminance rating (screen remains legible) in Settings? The operating time you get, as stated of 5-6 hrs seems pretty low. I get at least double that with intensive usage, and I mean it, THD Games! Keep in mind however that the screen of HTC ONE X, REALLY, IS the most power-demanding component of our smartphone and there isn't much that can be done about it.
As to your question, Villain rom is considered by many to be battery-friendly although pretty basic. In addition and if you have a rooted/unlocked device (I still haven't rooted mine because I'm perfectly satisfied with it for now), you can also give a try to the SetCore app that can be found i the Apps section of the HOX forum and as its name implied it allows you to control and deactivate cores at will. Also try out the well-known SetCPU app to underclock the processor and get more life from it.
Although, if you've purchased your phone recently, you may simply have to charge some more to condition the battery and then it will get to normal levels, of ~12-15hrs of serious usage.

first of all you do not need a rom that is based on battery life..all roms are the same with just few different modifications to it. choose a rom that YOU like and not based on what other people tell you. Then you can do a few things to get better battery life. as the poster above me stated you can do what he mentioned..but i still with autosync on, GPS on and autobrightness i can manage to get over 3hrs screen on time and over a day and a half battery life. Go into settings and sound and untick touch keypad sounds and lockscreen sound and dialpad sounds...come out and reboot the phone..you might think why but trust me that causes drainage to the battery and keeps the phone wake when the screen is off. second if you use twitter and facebook i would suggest to use them only when you log in..do not have it on in the background. if you still need more help PM if you like
but search for Touch Xtreme rom by Smarberg...that is a good rom based on battery more than anything else.

Im sure all the official updates are done. I use wifi in house and 3g when outdoors. Ive got bluetooth and gps disabled and as of now my screen is off automatic. Ill keep charging like you say to condition the battery but can you overcharge it?

I'm on stock and my battery seems to be OK.
The multitasking on another hand is shockingly bad.
Please someone give me aokp or cm9

I fixed multitasking with an init.d script that lowers the low memory killer values. All the apps stay in memory now without closing... like they are supposed to.
Some say HTC set the values so high to save battery, but that is crap. No power is used when the app is held in memory, infact less is used as the apps aren't constantly being opened closed and reloaded. I think they just messed up.
