[Q] How good is your Galaxy nexus's battery under "intensive" use?

Hi everyone!
After playing a few days with my new Galaxy Nexus, I was quite disappointed with the battery life of my device. It hardly survives a day.
I did a test today, trying to use the device more "intensively" by surfing quite a lot. The screen backlight was on automatic, bluetooth off, sync on, wifi on (although on 2G/3G most of the time this morning), nfc on, gps off.
The battery only lasted 5h30mn with the screen on for approximately 4h30mn.
I've attached 2 screenshots with the stats of the battery.
On a more normal daily use, I use the phone 1h30mn in the morning, check my emails in the day (approx. 30mn) and after work my battery dies after using it for another hour ... And that's when I don't have calls.
How is your galaxy nexus's battery life? Does mine looks normal or should I think about getting my battery replaced?
Cheers,
Laurent

Having the screen on for 4.5hours is pretty good imo, especially considering the size of it. Ive only had mine a few days so hard to tell but I think its matching up to similar battery life as my old Galaxy S..

4.5 hours of screen time is really good. My Desire usually makes me pay attention to charger after 3 hours, certainly after 4 hours. A high definition screen and more processing power Nexus surviving longer than that will mean the upgrade will be easy for me.
I am sorry that the OP is disappointed, but I for one hand predicted even less battery life. This is how battery life is these days with high end phones.

4.5 hrs of screen on time and you're dissatisfied? I'd say that's fairly good battery life for a phone not from the future.

4.5 hours of screen time is very good. I am getting about 3.5 hours on a normal day atm not tried what you have done yet.

Jesus, how did you manage to have the screen on that long lol

Very similar here.
1h in the morning on my commute. Probably another hour during the day, and then again on my way back.
As long as it makes it home to a charger, fine for me.
Although I have just ordered a 5000mAh external USB battery pack for when I'm travelling

Aye, like others are saying, 4.5 hours of screen time is pretty good. The iPhone 4 only gets around the same.
Then again, with intensive browsing and internet usage that's actually *exceptional*. The iPhone couldn't do it.

I'm using this one and I am very satisfied!
http://www.amazon.co.uk/TeckNet-Dua...kberry/dp/B000NDQ92W/ref=cm_cr_pr_product_top

iPhone 4 easily gets over 4 hour screen time. I got 2 hrs of screen time with 80% battery left.
We should compare to the galaxy s II which was supposedly very good for android

So you're upset that under an absolute stress test, you got ONLY 4.5 hrs?
That's pretty impressive. If not, return the GNEX and get, well, some other phone that will go 24 hrs under a full screen-on load test. Good luck.
Or just wait on generic batteries to hit eBay and buy three for $15 and be done with it.

Good news, that's what I ordered
Can you confirm it can be charged and the same time it charges a device. I.e a single USB mains adaptor would do me if both need charging.

I prefer something like this, because there is no cables at all. IMHO its best to always have one like that in your bag. It has two charging ports, mini and micro usb.

Pretty poor .. but no worse than most Android devices I have owned, I use them intensely: calls, wifi, GPS, wifi analyse, Fing, email, calendar, internet .... so I am never surprised! Just about lasts long enough to hit a charger in the late afternoon, in the car or back at base.

Yeah and it works with everything that has USB charging. It is no different from when you plug your device into a laptop that also runs on battery, etc. It is always great to have for traveling purposes, the only problem is that this item too has 'charge stress', aka you'll end up wanting to keep it charged 'just in case' but rarely using it.

Thanks all for your replies!
Of course I wouldn't use my phone with the screen on for those 4h30 a day. But it would have been good if the battery could handle 2-3h of web surfing, a day of standby with a call or 2. Unfortunately it often doesn't last this long on these conditions.
Apart from that the galaxy is a great phone.

Screen killing battery

hello my phone doesnt last 1 day of charge and it says 40% is due to display/screen can anyone help me?

You can lower your brightness if it is not already at the lowest setting.

Unfortunately, the galaxy nexus has poor battery life. You could also try turning off data when you don't need it.

the screen is at lowest and it doesnt make sense turning of data if the problem is from screen right?

I'm having the exact same issue. Screen is totally eating up my battery life. It took 30 minutes for the battery to go down by like 10%. And the screen is 40% of the battery life issue.

Maybe I just don't use the screen as much as you, but I don't find this to be true for me. I find it has great battery life. I don't sit for hours with the screen on, but I do regularly text and check emails throughout the day, do a bit of web browsing, take some calls, and play some Angry Birds or other games in the evening. The screen is always at the top of the list for battery usage, but even on an extreme day I still have more than 30% battery left by the time I go to bed. I throw it on the charger and I'm ready to go again in the morning.
I disagree that the Galaxy Nexus has poor battery life, in general. I would argue that: all high-end phones have "poor" battery life because of all the things they do (especially 720p screens), your personal use of it consumes a lot of power and you could benefit from an extended battery, or you have a faulty device.

hi there, i do that exact same things with no games, so less usage but i get less than a day... i love the phone but the batery is just no working...

I don't understand why people don't get that when you have a screen that is 4.65'' it will destroy the battery life. My screen use is always at 60% or more but yet I still get good battery life. The screen is going to use the majority of your battery when compared to other things, that's just how it is.

sorry but thats not the point, when you pay 700 for a top phone, that is suposed to be the google experience to carry arround wiith you and you can only get 10 hours of battery time something went wrong in the process...

Most phones are $600 to $700, and name one 4g phone that will last more than 10 hours with moderate use and no extended battery, just not going to happen. You need to reset your expectations.

GN battery is giving lots of trouble, too. I picked up the phone from charge and it was 100% charged. ! hour of usage with 3g on. Usage includes 1 hours or music and reading of pdf books simultaniously and battery is dropped to 61%.

I think you should take a look at every other android phone that has come out with the same specs in the last year. Everything from the EVO 3d to the thunderbolt have their default battery's not last more than around 6-8 hours with constant use because of the screen & processors.
THis is why Verizon offered the extended batteries at a discounted rate right off the bat, because default batteries have never ever lasted that long in topof the line smartphones. FFS the new iphone 4s I've heard from a friend that their phones don't even last 24 hours.
I have a galaxy nexus, and mine has lasted... let me see.. one sec...1 day 3 hours and 25sec's with 35% left. (of course I have the extended battery) but here's the kicker: the extended battery has basically the same back as the regular phone does. so if they so desired, verizon could technically put out another extended battery just like all the rest of the phones, but they might not do that. I'm content with the battery life as it is almost identical as the droid X from which I came. The only difference is since I have a lot of un-updated apps for ice cream sandwich one of them is using "mediaserver" A LOT. I'm talking about that being the top of my battery draining with the screen being second. They both have taken ~20% with android OS itself taking 13, PlayerPro taking 13, and other random things like calls and txt msging taking ~10% each.
So I would suggest not trying to watch a lot of stuff on your phone while on battery, or don't expect your battery to survive long while watching stuff on that great screen

hymn thanks for the feedback so the only solution I see would be to go for a bigger battery. I'm from Portugal were could I buy one and whays the power?

If your screen usage is less than 50%, it be more worried about what else is killing your battery........

[Q] Dead end with Samsung can I have your feedback please

TLR Anyone willing to see if their tab pro drains battery when fully powered off. Like overnight when you're sleeping or at work. Thanks
Hi,
I got a 10.1 tabpro back at the end of Jan. I thought it would be a massive step up from my Nook HD+ (rooted) but it's not. Not only is it slower than expected the battery life is atrocious. Samsung advertises over 2500 standby hours for their 10.1 tablet, I get 200. Also I get about 6 hour video, mp4 files, not 10 and I don't like a bright screen, I know companies exaggerate but this is daft. But it's the standby that's a problem, having to charge it every few days in case I want to use it is a big step down from my Nook.
It's been into Samsung repair 4 times now and I'm currently at a dead end.
Problem
It loses 0.5% an hour on standby even with wifi, gps, updates off etc
It loses 0.5% an hour fully powered off. Fully powered down. OFF, not on standby. Just to be clear
Compare this to my nook with a smaller battery capacity which loses less than 1% a day. I've tried turning off other android devices (mobiles & tablets) and none lose battery over 12 or 24 hours when powered off.
Current situation
It's been in 4 times, it has been returned with a squeaky corner which they've failed to repair and the retail box is torn and tatty like they played football with it.
I've now been told
I have spoken to our product specialist regarding this and the decline in battery life over the 24 hour period is not considered to be unusual. In the 12 hour period where the tablet was powered on, even though the screen is off and apps closed down the tablet will still be transmitting, searching for system updates or connecting to networks or wireless. The 12% decline in battery is considered normal for this kind of activity.

This doesn't address that wifi, gps, updates etc is turned off and drain whilst it's powered off. I responded 2 weeks ago but there has been no reply.
Feedback please
1. I've been all over the internet. I've tried greenify, I've tried battery calibration, there's a ridiculous amount of bloatware that I can't delete but I've reduced apps running as much as I can. Does anyone have any other ideas?
2. What's your tablet like, does it lose battery life when powered off? I've seen people posting on here about their 8.4 inch tabpro and they've put screen shots showing better standby battery life than my 10.1 with a much better battery capacity.
I've attached some screen shots, less than 3 days and it lost 33% doing nothing on standby.
I would really appreciate if anyone could feedback on battery life when switched off, is someone able to test theirs for me?
Many thanks,
Anna

Is someone willing to see if their tab pro loses battery even when powered off?
Thanks

Uh-oh. I hope this is unusual and anomalous. I'm actively seeking a replacement for my HD+. I want to love it. I *SO* want to love it but it infuriates me that the browser crashes so often. Yours? Which ROM?

Nook is fine, It's the Samsung that's utter pants. Nook battery loses less than 1% a day on standby and screen is good. Surprisingly I thought the octo core samsung wouldn't be laggy but it is, it's not that much better than the Nook.
I have cyanogenmod 11 I think. Yes the browser crashes but that's partly because many sites are badly designed and web 2.0 is badly implemented and I use Dolphin because I like the format however it's a terrible browser for crashing. The new Guardian site I struggle with on tablets and mobiles no matter what browser for example.
Anyone willing to test their tabpro for me????

I'm actually on my 3rd day with my 8.4 it's 10:35 pm and I still have 35% left

I don't understand. 3rd day of what, off, on standby, has it been used?
Mine loses battery at 0..5% an hour on standby and fully powered off. I'm trying to establish if other tab pro's have the same level of drain on standby and powered off. Can you give me more info please? Thanks

Take the rear cover off, disconnect the battery from its connector. Bring it to a repair shop where they can do a solder work. Ask them to re solder the battery connector, this rework only takes under 5 minutes. It will fix the problem of battery quick discharge. If the problem is still the same, you only need to replace the battery, cost only around $30 for new battery.

Thanks but it was only a few months old so well within warranty.
They replaced it with an tab s 10.5 (no more tabpro's available). Tab s gives me the battery life I expect and speed. Big difference between the two is the tabpro used up a lot of battery with 'tablet idle', well over 50% whereas on the tab s it's a few %. I think the tabpro didn't quite deliver, it was discounted quickly, the software wasn't right plus squeaky case, but so far imo they seem to have got it right with the tab s. Despite the lower capacity battery and bigger screen it lasted me over 5 days and that included setting up and installing apps. The tabpro by that point would have been long dead.

I'm glad you get a new replacement but this's a common problem of Samsung tablets . Be aware of this problem is the future of battery quick discharge. Most users just simply think this is a problem of battery.

Battery question

Guys,
can someone (2, or 3 people) post their battery estimated time left when the phone is 100% charged. I think i have a faulty one but i dont remember what was the estimated time left for a phone with good battery. I know its estimated but i have mine showing 15 hours left when 100 charged, so i think its dying again...
Someone? PLease?

three days and 20 hours, still on original battery.

My device Z1c rooted and Existenz custom ROM using...in my device it showing 1 day and 30 mins. So my battery is faulty...?

Your battery is dying. Time to get a new one. There is a thread for that issue here.

Battery currently 50% and says I have approx 1day and 1hour left.(stock Android 5.1)
My GSAM Battery Monitor says I get average 1day 19hr per charge with average over 2months.
I'm on stock 5.1 with root access and have my phone tool'd up with frequency/governor management and stuff like powersave governor for screen off and etc.
Battery use is very subjective on a wide range of settings, location, Bluetooth, WiFi, GPS, telephony signal strength, LTE and general usage patterns, so one person's setting/use will not reflect another.
That said, one should get 24hrs easy even with over 4hrs SOT.

The Z1C battery stat's reflect the current real-time usage and project the available time left based on what is currently happening.
If your phone is configured optimally and you don't use your phone over night, it should only use approx 5% of battery.
If you use GSAM Battery Monitor you can check if any apps are keeping your phone awake, number of time your phone is woken and high CPU users.
You can check for telephony signal strength.
My phone is 100% signal strength (very good)
How much power is used to keep your screen displayed, with dimmer better.
Also you can see if your phone is in deep sleep when phone is not in use.
Over a 12hour period my phone is in deep sleep for 9hrs.
Use another phone for a couple of days and leave the Z1C with screen off for those few days.
If not used you should see over 3 days of battery life.
There is no answer to your question.
At the end of the day it's up to you to optimise your phone as best you can and base your decisions on previous battery use/experience with your known workloads.
If you're not gaming for a day or two and you have your phone as optimised as you can, then, 15hrs is crap and your battery is on the way out.

Sony Xperia Z1C Battery
Attached is a snapshot of the battery use in my Z1C running Android 5.1 stock with root access.
As noted, when the phone is not in use the battery almost flat-lines with very little use.
When battery use is almost a perfect triangle on the two axis and from 100 to 0%, then it's a good indicator the battery is failing/failed.
Replacing a battery on a Xperia Z1C ...well it sucks...to say the least :crying:
You need to add additional adhesive on the top left near the camera location as that's the area that tends to come unstuck after the back cover is replaced.
Also good batteries for an Xperia Z1C may be hard to find now.
The original batteries are marked with the manufacture date as yy-ww (Year and week[0-52])
If you find an original battery AND it DOESN'T have the NFC conductor glued on it, then you have a good chance of getting a good battery.
If the NFC conductor is glued onto the battery, then there is every chance the battery is just an old one pulled out of a previous Xperia Z1C.
Good luck.

Thanks man. How much SOT do you have in a 100% cycle? Your battery seems like awsome watching that print screen.
My little z1c is a frankenstein. I already changed the battery one time, the back cover 4, times. I repaired the mic, and changed the screen two times.
My screen is a generic one wich must be set to 100% auto brightness.. That also affects battery, but even so i think my batt is dying...

A tube of glue and an Xperia Z1C are almost synonymous with each other these days.
I had to glue the bottom speaker cover and the magnetic charger back on again... plus the back cover several times.
Currently I have used 25% of the battery and 2hrs SOT as seen in the attached.
I get a reported ~7hrs of on screen time per 100% charge cycle.
Email, WhatsApp, web browsing using RSS in Opera Mini, Tapatalk, Shopping apps, system/file management, Youtube and etc... (No gaming nor social Facebook, Twitter, Tinder...and etc)
Deleted all Bloatware out of /system/app and system/priv-app.
Update - ..ummm.. is Clash of Clans and Battle Command gaming...me thinks not.. but maybe it is.. ..any way throw a 15min mix of that into the pot too.
If you're not using much CPU you'll get more SOT, which is why gaming is a bad indicator as it's hard on CPU and screen, unless you have a game that does not get updated anymore(known stable unchanged test environment) and you benchmarked it a few years ago.
Then you can use the same game as a good indicator for any current status changes.

Battery Reducing Quickly?

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help

If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.

Best way to go is using normal charge an never let the battery drop below 20% forget about trying to maintain certain range (60-80), it will just drive you crazy

If I put my iPad mini to sleep at 100%, I wake up the next morning with 100%. Maybe 99. But usually 100.
That's not the norm, and it's not perfect apples to apples, but it is possible.
Also, 2 days of standby with zero use is not unusual, but definitely not "crazy good".

It went down TO 2% not down 2%.

That's not what he said. Read it again.
"Would this cause my battery to go down 2% in an hour without any use? "

Wow that is unusual. Do a search for "sleeping apps" in setting and add all the apps you don't need running in the back ground. Also in device care > battery you can see what app is using your battery.

So besides that little fight you had with the other forum member (lol) I appreciate your comment. But there seems to be back and forth, one other person says its good, another says its not. (the one I quoted below). Just seems weird to me that with no open or running apps and just the always on display running that it went down in an hour in 2%. Searching around, people saying losing 1% In an hour with the same set up, no running apps with AOD is bad. I kind of agree since its not truly in use. But unfortunately I cannot find any battery standby tests from Samsung or anyone else to confirm it.

I agree with you more honestly that it shouldn't be going down that fast in an hour with just the AOD running. I didn't have any apps running once it 100%, I was on it while charing it to around 50% but then once I knew I was putting it down for a while I ran the optimization and had the phone kill all the apps. When I saw it go down the 2% I did check out the apps using the battery and the AOD was the only thing listed. Maybe I didn't charge to a full 100%? even though it said 100%... Ill check it out tomorrow once I charge it fully again, today I was charging it up and down most of the day sadly. I try and keep most apps from not running in the background, some I do need though like for my IoT devices needing to know my location, I have yet to change that to just using LTE as my location GPS, but that was not on last night all. Ill try out the sleeping apps though, I didn't know there was a setting for that. Thanks again

AOD typically consumes 1%~2% in my past note devices(7,8,9)

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.
However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.

Reporting my battery life. I guess this is truly an all day device.

Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

In an hour? Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use.

This is useful, thank you. Never knew not discharging device is the way to go but we all learn new things every day. I'm at 65% right now, when waking up at 6am with 95%. Wireless android auto for about an hour, plus okay-ish use. Ill make sure to charge it up to around 80% tonight.

Thanks, I think I am seeing a bit better today after having it for 4 days or so now? Ill follow the above quote about calibration and go from there.

Over 8 hours screen time is great, best I've gotten so far is 7.5 hours

I just wanted to throw my two cents in here... My battery life is pretty terrible in comparison to my S10+. Trying to find a rogue app of some sort but I just hit 1% with 12 hours off the charger. Keep in mind that is not 12 hours of use. In fact I used it for about an hour of total screen time today.

Yeah I came from an S10+ and noticed my battery on the N10+ was pretty bad in comparison.
I did restore everything from my S10+ though, not a clean install of everything.
Wonder if that may be causing issues.

Is everyone having problems on Verizon?

Quote " Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use."
Unless you put it in airplane mode, your phone will keep connected to cell tower (or wifi if you have wifi calling) otherwise you won't receive calls and messages, so there is no such thing as phone with no use, and if you have weak signal or some interference your battery usage can increase drastically even in standby because the cell radio will try to connect at full transmit power. And then you have all those programs running in the background, God knows what they're doing. As others suggested disable programs you don't use, also you can force close programs that you don't use often. When I had my older Note rooted, I optimized it so well it would run 2% down per 8 hrs overnight, but it took some effort. Biggest problem is to know what to disable without loosing functionality for stuff you need. Give it some time for people to learn more about new phone. BTW my 3 day old phone has 435 apps and services installed and most of them I have no idea what they do.
