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...

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?

Sounds like the solution for you is simply not use JD.
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.

u know what , ive been using android for two years ( htc , samsung , lg ) and dont judge me as using this phone efficient , I have knowladge about computer and smartphone almost your age

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"

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.

[Q] Constantly in a bad reception zone

When I'm at school (5 days a week) most of my classes are in a building where I do not get a lot of reception, aka, my battery gets killed by the phone to keep up the signal. I do get reception, around 1-2 bars, but that still drains the battery extremely fast. Is there any app or something that I can do to help reduce the amount of battery drain?
I don't want to put the phone into air plane mode because I can still send and receive text messages, but it's just very slow.

Have you tried putting it in cdma only mode?
Sent from my Galaxy Nexus using XDA

You could save a lot of battery life by either connecting to a wifi hotspot (if available) or by turning off background data. The problem your phones having is that it has to turn the gain way up on its cellular radio in order to transmit and receive data. By reducing the amount of background data usage (or off loading it to another network with better signal--i.e. wifi) you'll save a lot of juice.
If you can't do either, there are some things you can do with Tasker to reduce data usage to windows of time instead of always on. May be something to consider.

Battery life without data on?

Hello there I'm looking for a reasonably priced unlocked Android phone to take abroad with me this coming fall. I won't be using data services so that being said, how long would the battery be expected to last with moderate to high usage? (good bit of texting, some calls/pictures, and some wifi Web browsing). Thanks! Searched around and couldn't find this bit of information.
Sent from my SPH-D710 using Tapatalk 2

How are you expecting to make calls? If you literally only have a voice-only SIM when you're there and you'll be using the phone heavily on WiFi, the battery life won't be drastically better than if you were on mobile data. The screen is the largest drain on the phone, and if you're still using data over WiFi you'll maybe get to 2 days of usage on a stock phone.

There's an option in settings to turn off data. You still get voice, you don't need to turn on airplane mode or get a voice-only sim.
But I agree, battery won't be drastically better, I have data turned off and my batt times have been similar to the average times posted here

Yes I know you can turn off data . I asked how he intends to make calls because if he will actually have a SIM in and connecting to towers for calls, battery life will not be drastically better than if he had data turned on. If, however, he was making VOIP calls over WiFi with airplane mode on, he'd likely see a large improvement in battery life.

Yeah I realize keeping the antenna on will consume battery...I would probably be surfing the Web on wifi for 30 minutes to an hour max each day. Should I look at getting the extended battery? As long as I can get a full day (18-24 hours) with moderate to high usage I'm fine.
