Hi,
I am considering buying a Hero, but wonder if anybody can let me know how long the battery will last if I am using it only as a mp3 player.
I am think of when I am on a plane and wifi, bluetooth and the phone are all off, and just the media player is playing mp3s.
Any idea of average battery life?
Cheers.
With my Hero the battery-drain is very minimal, when using mp3 player.
Same with me - the MP3 player uses very little battery. Not sure how long it would last, because I have never tested it, but my guess is much longer than a transatlantic flight.
i'll tell you exactly how little battery the music player uses with an example.
I had been using my phone all day at school browsing and texting and games etc. By the time it was time for me to go home the battery level was at 3%, I needed my music to get home its long ride on the subway and the bus. I went into airplane mode and the battery lasted me all the way home approximately 45-50 minutes that was on 3% battery life.
So you can guess how long it would last with a full charge.
about 14~15 hours at least,,
I am a long time owner of the Galaxy S that has recently bought the S II.
Comparing to the previous model the S II heats up real bad with my usage and the battery drains incredibly fast. When running 10 min of flash video, my battery temp shoots up to over 50C and it drains over 20% of my battery. This is even with the May 11 ROM release.
So i would like to ask other owners to post their results with a flash video as reference (i used the video on watch futurama online S2E1 as my test if you could use the same one maby). Running full screen for 10 min at lowest brightness what is your battery temp and how much battery is drained (i use Smart Battery Monitor to get those values)?
Thank you.
I think it's Flash - it will always be a power hog.
720p YouTube video doesn't even run smoothly on my Macbook Pro, so it's going to be a challenge for the SGS2.
Its not just flash. Games, market and some other stuff also causes the same thing. As i said Galaxy S didnt have such problems with runnin flash or any other content... i want to hear from other users if they are expiriencing the same problems or if my cellphone is defective.
When it is on standby it is lik 1% -2% an hour. When I just touch it and play some games or browse the web, I just see the % go by fast.
Yesterday i downloaded some games, browsed the web and played the games. 26% lost in 45 minutes.
So its not just mine.. this sounds horrible. Anyone else confirm this? Also post the 10min test result with temp and drain?
I played a game for 20 minutes, lost 20%. And that's with almost all games.
General usage - 35c
Heavy usage - 40c
Idle - 29c
Charging with no usae - 41c
Charging with usage - 44c
And when i put my case in the temp increases about 4c on average... So now when i charge it i put it near my air con. Battery is good lasts me a day

So battery does drain that fast... what is heavy usage for you?
Can you please just run 10 min of the video i did on wifi and tell me what peak temp you get exactly with it and exactly how much it drained the battery... anyone just so i can compare my results, its just 10 minutes of your time.

Really??? Videos 1080p Youtube run smoothly on my GS2, no problem at all. After updated to the newest firmware (KE7), CPU temperature is noticeable lower when playing game for me, and battery life improves too
I noticed a decrease in temperature with latest firmware too, but how much exactly is your max temp now? Give me some numbers...?
I had max 41c after 15min of game and down to 32c after 3min
Thank you. After the last update from Kies i also had a max of 42C after 15 min of watching a flash video. Before the update the same flash video made it shot up to 58C.
I decided to run my own battery test this morning. I created a 720p video copy from my Cars blu-ray. Copied to my Evo LTE, and started playing it on MX video player. It will play the movie over and over until I stop it. I'm trying to simulate watching video on a long flight, so I put it into airplane mode. Brightness is set to auto.
So far, the video has been playing 3 hours and 25 minutes. My battery is showing 66% remaining. So far so good. If the battery percentage is accurate, I should get 9+ hours out of this, possibly 10. I'll keep it running and see how long it goes.

Awesome! Can't wait for your results.

It's been playing for 6 hours now and the battery has 40% left. The phones seems to use about 10% per hour. Let's see if it will get up to 10 hours.
So far, I'm very impressed. My old Evo didn't last long at all playing videos during my plane flights.
Oh, and I forgot to mention, the 720p video looks amazing!!!!
Mark
Ok, so I stopped the video when my phone hit 10% battery life. The phone continued to use approximately 10% of the battery life per hour. So the final play time was 9 hours and 8 minutes. It would be very close to 10 hours if I kept going. Excellent battery life if you ask me!
(the screen shot was taken after plugging the phone in to start charging her back up. that's why you see 11% and the charging icon)

Not to shabby. It can only get better with some custom ROMs & Kernels, to maximize battery life.

Really? He gets ten hours out of a mobile phone playing 720p video and all you got is "Not too shabby"? When my Galaxy Tab was new I did a test with a video at native resolution in airplane mode and got like 5 hours of video. Considering the size of both batteries, I'd say ten hours is fricken bloody phenomenal.
As a different comparison of usage, I played about 3.5 hours of video over wi-fi on my LTE on Friday. The first half hour was through the flash player, and the latter 3 hours via the twitch.tv app. I did also have it off the charger for like 9 hours entirely and made a short phone call too. Not only is the battery on the LTE amazing, the frugalness of the hardware in using it is also.

lol. +1. This is so true and funny
Here are the video details if anyone is curious. I'm not sure if things like bit rate affect battery life.
just for comparison.
i did a similar test with my OG Evo, 4 hours it would play movies then it shut off at 0%
OP, your results are impressive. Can you post more information? I'd like to know about the audio stream. And also at what speaker volume were you playing the movie?
Hey guys, I'm just sharing some knowledge that I stumbled upon 2days ago. It concerns video playback and conserving battery power on our Ace.
I use MX Video Player for viewing videos and like most I would just copy the .avi file or mp4 file straight onto my sd card. What I also try is to underclock the processor to conserve some battery and the speed I would usually use is 614mhz, to get a smooth playback.
However over the last couple days it just hit me "let me try to convert that avi file, see how much space I can save" so I fired up AVS Video Converter and chose the android tab and found the ace screen resolution (480x320). A typical avi file is around 700mb but with the conversion, most files are around 380mb, but that is not the great thing. Upon further inspection, I get smooth video playback (i.e. around 30fps) while using a very low cpu frequency of 245mhz.
Now I did some testing and waw, what a difference it makes I got like 5% battery drain for every 30mins of video played which is a lot better than the 614mhz.
I just thought I would share this for anyone who uses their phone to watch movies while out and about, it can save you some good juice, give it a try, it worked wonders for me.
Ok guys I did some more testing and this is what I got:
I tested by watching the same video clip (28mins) and recorded the amount of battery drain, then I let the phone charge back up to 100% and did the tests again using different frequencies. I did a stock (800mhz), powersaver (614mhz) and finally the ultimate battery (245mhz)
STOCK (800mhz)
14% battery drain
Powersaver (614mhz)
9% battery drain
Ultimate battery (245mhz)
5% battery drain
Note that the cpu governor was smartass v2, I did another set of benchmarks with the ondemand governor and I did not notice a big battery hit, only at the stock (800mhz) where the battery drain increased by 1%
EDIT: also I was not using the loud speaker, I used my skullcandy ink'd earbuds with the volume at 3.
I got more battery drain
I watch 6 hours movies anime etc
Then battery is at 25%

Hummm...that is strange, i've been getting really good results
Battery reading are pretty awful on ace
Interesting, I tried to underclock my phone's cpu power to 245MHz but the video play was not smooth at all, I then finally kept it at 320MHz
Why you used MX player? Coz video quality is good only when SW decoder is used, which is hell laggy at low Mhz. You could also have used integrated video player with the same settings you mentioned.
Any thoughts...??

I really did not try that honestly, and it uses the HW decoder, I don't choose, it selects it automatically.

6hours is good, no? How many hours of video/music playback is the phone supposed to give? Can't find the info anywhere. Also where do you leave your brightness setting to?
I got a free S5830 from someone who upgraded to something else (rooted it, installed CM10.1), and i get only 2 1/2 hours video playback (or even when playing around with settings and the screen is being used - was the same with Gingerbread 2.3.6). I'd think that the battery needs replacing (has Aug/2011 date on it), but when it's left on standby the battery drains at the normal pace it's supposed to drain at. Does that still mean the battery needs replacing?
Are you using the original Samsung battery or did you replace it?

If I play games on Cm 10.1 the battery lasts about 2 hours. So 2 1/2 hours could be normal.

Thank you for sharing this, i will definitely try this out when i next get the chance
i could really do with more playback time.

Considering how quickly the battery drains on my ace, i'd say that this is a good amount of time
Hello, I recently acquired the red magic 7 supernova, and I would like to know your experience regarding the battery issue, I obviously use it to play, and playing games such as genshin, 60 fps high graphics (not at its maximum) consumes almost 40% Battery in 30 min, that is ok? I do streams and I use only for games and daily use. I end up charging it about 3-4 times a day, would that be a problem or could something be wrong with my battery?
The smartphone consumes little both in Active and idle, this in normal use, during the game has high performance and three different power management settings, if you use balanced and 60hz it lasts you slightly longer. It is advisable to use charge separation to exploit it to its full potential for long gaming sessions.

You can always play on a charger with "charging separation " and you want lose battery
