ICS 4.0.3 Battery Life

[dwykofka]

How is everyones battery life on ICS compared to Gingerbread?

For me I am seeing twice as much battery left at the halfway point in my day.

My previous measurements in Gingerbread had my phone sitting at 30% at 2pm on an average typical day at the office with 2 exchange accounts and tons of email.

Today what I am seeing even with lots of playing around with ICS is 63% at 2pm which is more inline with what I was seeing previous to the Gingerbread update.

I noticed in gingerbread that my OS consumed more battery than my screen. With ICS, the OS consumes levels of magnitude less, but the display now consumes almost twice as much... I have a live wallpaper (this should go on OS while screen is turned off though). I have the screen set to minimum brightness and 15 sec delay to shut off. I got no explanation on why it uses much more... Overall, I'm having the same battery consumption.

my consumption yesterday after the update was huge, but I was using the phone heavily. Most of it was voice calls and screen. I have my screen on auto. Just did a factory reset. I will vote in a couple of days after things settle down.

At 11.5 hrs, I am still at 60 percent battery life. That is after a day of heavier than normal use including taking and uploading via 4g around 20 pictures. Recording a video and uploading via wifi. Having sync on all programs... gmail, facebook, and exchange. Standard texting, and generally messing around with it to see what ICS has to offer.

I would probably be in the 30% area with Gingerbread and sync turned off for all apps. I did turn off wifi and gps during the day out of habit with Gingerbread.

I'm liking it.

For the record, do you want only stock ICS, or do you want to hear from rooted users as well?

That's a good question, I was thinking this would be a good comparison between the samsung/att Gingerbread and the new samsung/att ICS. Ideally it would provide some information to users that are contemplating upgrading to 4.0.3 in order to fix the battery life issues introduced in the previous version.

With wifi on... I am not impressed so far. I will turn wifi off and see what happens.

 

[dwykofka]

My test were with wifi on and at the point I normally would have 30% I am above 60% with a lot more usage.

Having said that I was a victim of the Gingerbread battery drain bug and the huge increase may just be a artifact of that bug going away. People who didn't have the Gingerbread issue may not notice a dramatic change.

I'm about the same.

- WiFi, GPS off
- Sync on all apps
- Display 100% brightness
- No power saving
- Approximately 45 minutes of voice calling
- Approximately 1 hour of text messaging
- Display was constantly on today, as I was tinkering with ICS for the first time.

I was able to get Gingerbread 2.3.6 to last two days without a charge and still have some battery to spare, but that was with bouts of very little usage. We'll see how ICS goes...

 

[wolfyboy359]

I have android system is 33% of power usage and voice calls 35%. The rest is cell standby at 13%, screen at 9%, etc. Is that normal for the android system to use so much power?
On a related note, I tried to take a screenshot of my power use screen, but I don't know where to go after you press the power button then the home button. Where does the picture go?

 

[gianmarco]

I am just hoping the wifi bug of 2.3.6 will no longer be an issue....

 

[wolfyboy359]

Ok , I just voted, and said it was worse. at idle it's about the same, but when I use the phone for voice calls or wifi, battery life takes a nosedive.

So, it's not my imagination. I find the same issue.

Try calibrating your battery? Seems like it was a key point with GB and quite likely, it is with ICS as well.

@louwags: could you please post a link to the post that describes how to calibrate your battery?

 

[nyydynasty]

this poll is a little misleading because battery life is primarily dependent on personal phone usage. My so-so ICS battery life may not mean anything because i might use more data-intensive apps that cause wakelocks (just an example) and it isn't the fault of ICS at all.

it all depends on the phone. Some phones don't need battery calibration (like the i777 GS2) - at least according to some GS2 devs over on XDA.

 

[dwykofka]

With enough data points you can make some correlations to in regards to whether battery life is better as a whole or not.

 

[SobeStyle]

I noticed about 15% better battery life so far. Usually my phone is fully charged when I go to bed and 15% when I wake up and now its about 30% when I wake up. God awful battery life but now a tiny bit better. still not acceptable if you ask me but still better.

I do not use my phone for talking, all data and text. Wifi left on Gps off. Animated screen saver on always

I will get the S3 if the battery life is better, I cant imagine it being worse so I probably will get the s3 but NOT in blue or white... will wait for black to come out on ATT

 

[jej826]

Much better battery life.Before update I would be around 35% at 1PM.7 hours after removing charger.I am at 15 hours now and still have 62% charge.This is with moderate use.

 

[robhs]

Battery life was half what it was before my upgrade from GB. I did a hard reset, and now battery life is the best it has ever been.

Stock, unrooted, by the way.

 

[wolfyboy359]

I am having some sort of problem with my screen using up all my battery. Flashed a new rom and same thing.

same here. hard reset and my battery lasts much longer.

 

[zs3889]

it seems like everyone is getting better battery life, not me though, it consumed more when i left it when i go to bed (idle). are you guys using touchwiz launcher or some other 3rd party launcher such as apex or nova?

I'll have to find it. If I do, I'll put it here: [Couldn't find it. See below.]

You're probably right but it's something else to try if you're still having problems.

Some further observations: I left my wireless on yesterday and also installed a stock watcher app. The app constantly updated throughout the day and within an hour, the battery life slid WAY off. Still, it was at over half when I finally checked out for the night.

Today, I've left the wireless on and I'm at 75%. Tomorrow, I'll shut it off and see how that does.

--Wag--

 

[LouWags]

From my flawed memory, to calibrate your battery, let it drain completely. That is, until the phone shuts off. Help it quit by turning on EVERYTHING.

Plug it in and recharge it completely. When it's fully charged, unplug it. Then, IMMEDIATELY turn it off. Leave it off for about 30 seconds, then turn it back on.

All the stuff you turned on in step 1, turn it all back off so that you have an apples to apples comparison for whether or not this did any good.

I'd be very interested to know if this helps. It seemed to do a world of good when I was on GB.
