[Q] Battery issue?

Here's a screenie from my battery screen, I know the battery is a common problem, but when I see shots from others battery screen their screen and OS percentages seem much lower. My screens set at about 20-30%. Just wondering if I'm doing something wrong, or any suggested apps/roms you have. Rooted CDMA.

Te longer you have the screen ON and are using the device then the more power it uses over a period of time

Tap on the screen % to see your screen on time. This device currently sucks a lot of power through the high pixel display. You can switch to manually adjusting seen brightness to save some battery.

Looks fine to me. My android os is usually around 15% or so depending on how much I use the phone and I get great battery life.

@rbiter I am curious how long has your Galaxy Nexus been running before it turns off? I have gotten about 8.5-9 hours the one time i ran mine all the way down. That is with auto brightness on and lots of browsing and no games and some calls.
Frankly I have been disappointed with the battery performance so far. I love the phone of course, but just wished they would come out with replacement stock batteries so I can go as long
as i need, without having to swap out the backs etc.

You could always just use the extended battery w/ the extended battery back cover. That cover works also fits pretty well with the stock battery.

[Q] Battery Life vs S2

Hey,
I'm hoping to get some feedback from the Nexus (i9250) users here that either own or have previously owned a S2 (i9100).
I'm considering letting my S2 (running CM9) go for a Nexus and I only really have one concern: Battery Life.
I'm interested in 2 different scenarios, if anyone has a view on it:
1) Stock: Nexus 1750mah vs S2 1650mah
2) Extended: Nexus 2000mah vs S2 2000mah
Technically I'm more concerned with the Extended scenario considering that is what I'm running on my S2 in order to get through the day without any worries.
Thanks in advance for any feedback

Galaxy Nexus has better standby (means if you keep display disabled and have only things like Bluetooth, Data sync and Wi-Fi running it will last longer than the sgs2) but the Galaxy S 2 have better display-on-time (because of the smaller screen of course). I guess the display-on-time of the galaxy nexus is around 4 hours and the one from the sgs2 is 6 hours.

@blockbusta: Thanks for that bit of information. I will monitor my screen-time usage over the next couple of days to see if my usage would allow for the upgrade to a Nexus.

I used to have an S2 with a 2000mAh battery, now I've got a Nexus with a 2000mah. The Nexus is definitely worse for screen on time, but is a lot better for standby which makes a huge difference. The Android OS doesn't savage the battery like it does with the S2, and you can keep wifi on and the drain is minimal.
With the extended battery and Franco kernel, I can usually squeeze at least 5 hours out of it, with decent standby time.
To put it simply, I was disappointed at first doing the same trade you did, but have grown to get used to it and learnt how to squeeze good life out of it.
Hope that helps.

@Remoteconcern: Thanks for the info, it definitely does help. As long as I can manage to get 17 to 20 hours out of the 2000mah battery, it would be sufficient for me (but that all depends on usage, and in this case very much on screen-time it seems).

Did I get a defective battery?

Just got my s3 like a week or so. I made a mistake and not charge it initially (thought it was a myth). I used my battery all the way to 17%. Now my battery only average up to 2 hours screen on. My sister who also got the phone as the same time has about right hour screen on time. Did I screw up or it's just my battery being defective
EDIT: attached is the battery stats

What's brightness set to, and what are you doing while the screen is on? You on WiFi most of the time?

Well, when I'm in door, I use low brightness most of the time. Only when I'm outside I would use auto brightness. Since I'm in wifi zone most of the time, yes I do have wifi on. I mostly use my phone for twitter, web browsing, and youtube, nothing heavy like gaming or benchmark.

Hard to say if its defective but I've definitely seen a lot better battery. It might not hurt to try and get a new one.

you should calibrate your battery a couple times once you get the phone. do it a couple times and it will fix itself. also check all your syncing settings. this phone will deplete a battery in 5-6 hours if fully charged and phone brightness is up all the way while watching videos.

Calibrating batteries is a myth from the days of older battery technology. Draining your battery to 0 on purpose is actually killing your battery faster because you just used up one cycle.

There's a bug on stock that makes cell standby much higher than it really is. So I wouldn't worry too much about that.
Also, Google Chrome is a huge battery killer for some reason. Consider switching to a different browser?

Still having the original battery in my vibrant and getting 8-9 hour charges while killing the battery 100% and charging it up once a week does nothing? Same thing for my g2x. I get about 10-11 hours on the thing daily original battery as well. If anything and you're not rooted to delete battery stats, its a good thing to do a couple times. I don't think I have hurt the battery at all, and if anything they still last very long...

I bought the Chichitec 2500mAh extended battery pack and they work very well. I get on average a minimum of 4hr screen on with lowest brightness as oppose to 2hrs and change with the stock. I also use jucedefender and I rarely talk on the phone. I would recommend them.

I have that one, it isn't bad, but it isn't great either.
Typical Chinese quality (Samsung is spelled Sanmsung and Galaxy is spelled Galyxa when you actually get it).
Battery life is, well, I dunno. It's hard to say. My phone was at 57% charge, I turned on the extended case and without any use it charged my phone back to 100% no problem but the extended battery was pretty much dead. I'm sure it works better when both the phone and extended are charged to 100%. The AC/DC converter inside the case is VERY inefficient and gets VERY hot. Don't even bother attempting to charge the extended battery while the phone is in it, I'm suspecting it will catch fire or melt lol...
I like how it has a power button and the kick stand works. The case is very sung and everything lines up properly so for build quality I give it a 10.
The USB port pass through is CHARGE ONLY, data pins are missing so it kinda sucks if you use OTG devices or need to plug it into the PC to transfer files etc. But all in all you get what you pay for.
My friend has the Hyperion 4200mah with NFC. It works excellent, double the battery life. He usually gets 3-4 days with normal use out of the phone without charging (but that depends on person to person).

Here are some of my hyperion 4200mah stats

This is also with heavy usage... Hence the 51% screen time

I just bought another oem battery and always have an extra one on the wall charger. I probably swap out once a day.

Setting new battery capacity after replacement

Hi, guys.
I've just replaced phone's battery with this "HSABAT 3800mAh" ... Everything is ok but I'm guessing the battery percentage info in system is adjusted to old 2300mAh value. I'm using AICP Oreo.
What I need to do in order to get accurate battery data??
Thank you in advance :fingers-crossed:

I think you have noticed by now that it all works without any additional settings.
However - i do not think the new battery is 3800 mAh - at least not in this phone (voltages). The battery tech has not evolved so much during these few years and the battery compartment physically does not allow so much energy. (you need to have certain amount of chemicals for any Ah).

Everything is OK, except for battery life... I guess this "HSABAT 3800mAh" was a rip-off.

I'm not sure if I should try another replacement battery.
It's a shame be forced to say goodbye to this nice device because of this.

Just buy a genuine battery, they are available on the internet (about $15-20). I have replaced my battery twice with full success.

Just stop and think a little bit before buying. Original battery is 2300mAh and your fake one is 3800mAh. How on earth you can pack almost double capacity into the same size battery? The same chemistry gives the same capacity in the same size. Simple. Forget about 3800mAh and if it holds charge properly just use your phone. Probably you still have 2300mAh in it.

You can use your current battery if it holds charges properly e.g. no sudden drop from 50% to 0%. I got my battery a year ago from this shop and it works fine https://www.aliexpress.com/item/32870459998.html?spm=a2g0s.9042311.0.0.1ec633edTwqvQZ
