I just bought an Xperia Z phone and tablet yesterday and was pretty exited about it! It works really well, I love the design work and, yeah its just great. Only thing is, the battery is killing me, here's why:
I woke up this morning and unplugged my phone from the charger, it was at 100% of course. I sat down in my couch, checked Facebook and some News websites. Literally 8-10 minutes later, my battery percentage is 91%... 91%!!!!
My brightness is at ~40% no running apps in the background, no live wallpaper, WiFi on, latest Android update.
Is this normal? I was used to my Galaxy S2 lasting a lot longer, and I know I can't compare the two batteries and phones, but if this problem persists, this would mean I wouldn't be able to use my phone for apps and whatnot for more than 1h20m without having to charge it.
I got it yesterday, turned it on and configured the phone without it being in the charger, it was on ~50% when I turned it on and when it reached like ~20% I plugged it in the charger, I don't know if this could have damaged the battery, should I've plugged it in the charger right away? I am saying this because I remember on old cellphones (not smartphones) to get the best from the battery you had to charge it non-stop for like 20h or so.
Sigh, this is a bit frustrating. My Xperia Tablet Z has a great battery btw., absolutely no problem there.
The Xperia Z phone has screen time of 4hrs or so. It's primarily because of the 5 inch 1080p screen which consumes a lot more battery. I have owned my Z for two months and I get a day out of it with 30% battery by the time I hit the sack. For me it lasts 15 hrs or more.

how can people stand 40% brightness? its like killing my eyes.
i do 0% brightness with auto on. saves me alot of battery.

Do comment only after giving the battery multiple charge cycles. If the same problem persist after 2 weeks, yes you probably need to check what is sucking up the battery.
Do take a look at the graph under "Settings" -> "Power Management" -> "Battery" to take a look at what is the highest consumer.

Ok I will give it some time, but it doesn't look good.
I've lowered my brightness to 0% and the power mgmt tells me that the screen is using up 40% battery, I don't get it..

It means out of all the battery power used, 40% of the time the screen was active and consuming power... I think
Try these
I used to complain like u did at the beginning, but i tried doing these things and it really improved my battery performance....
1- 1st of all it will get better after a week of charging discharging cycles
2- I uninstalled moxier pro
3- Deactivated google now
4- Disable bravia engine 2
5- Disable google chrome and use another browser (boat browser is really awesome and it supports flash)
6- Disable access to my location from location services and activate it only when u need it
if u do these things u will have marvelous battery improvements!!

It actually means of all the drain, the screen accounted for 40% of it.
Just as the title says is the power saver options like CPU and data connection really useful as well as the "sleep mode" option in power settings or are they making battery life worse?
If they are power savings options i don't see any reason why it would drain even more?

well according to this quote from another thread on xda in the sprint htc one forum,so I wasn't sure because it says it does make it worse.
"Power Saver mode will not save you any remarkable amount of battery unless you are maxing out the CPU or GPU (like playing games). Since what it does under the cover (besides what it advertises in the options) is downclock the CPU, this can actually be a detriment to battery life. It is better for battery life for the CPU to run at max speed for very short periods, and then go to sleep. It uses more power by running slower (and thus staying awake longer)."

Anyone?
I keep the power saver on most of the time. The main things I notice is that it dims the display (not really an issue if you work indoors) and it disables the wifi and data connections after periods of inactivity.
No real downsides (I'd be curious to hear other people's experiences). Sometimes receiving WhatsApp messages takes a couple extra minutes if the data/wifi connection goes to sleep.
Seems to give me good battery life - I average 15-18 hours, and that's including a fair amount of on-screen time and music/podcasts during the day.
I used power saver quite a bit in the 2 months after I got the phone but I don't use it anymore. In my experience it helped very little (as in added an hour or 2 maybe to overall life per charge). My baseline average battery life is 21hrs GSam tells me, and that's without power saver on at all (wifi, nfc, cellular always on and screen at 100%) and about 3hrs screen on time.
It may just be that, as was mentioned above, my use doesn't utilize the benefits of power saver because I don't often do cpu intensive things. It did run a bit cooler though. I also prevented the mode from diming the screen. I always (and still do) found that most of my power was going to the system (apps etc) @80% even with the screen maxed, and that I would lose about 20% overnight with our without power saver. So I stopped using it because : 1. It didn't improve MY USE 2. I didn't like the notification icon 3. I hear really good things about Battery Guru from experienced XDAers and the app seems more intelligent than power saver to me so I use that now. Unfortunately it's still too early to tell how much this will increase my average usage.
Regarding the issue of damaging your battery, the way it was brought up refers to the number of charge - discharge cycles a battery has. So only something that discharges the battery more quickly (so that you have to do another charge cycle more quickly) will shorten the battery's life. If nothing else, logically using power saver would not do this. It won't hurt the battery and may not hurt your usage (remember the GPU can still run at full clock for games), but I don't think it will help you much either based on my experience.

dont believe everything you see online. All it does it limit the CPU, as opposed to running 1700mhz, its capped at 1134mhz, this is not detrimental.
it takes power to make power, undervolting and downclocking processors has been repeatedly proven to assist and aid battery life.
it takes a certain balance or the two to get great results. Mind you the stock kernel is great but its adaptive. So dont be discouraged when seeing bad battery life initially.
If I leave my phone off charge overnight, I usually loose around 5%. If I turn powersaver on, I only loose 1-2%. This is with around 8-10 hours of no usage, with wifi on. It also turns off vibration feedback when using the back and home keys.
I've also noticed the phone to be slightly less responsive with power saver on. As far as I can tell, if you are concerned whether your battery will last you the few more hours you need, it will definitely help save power
It makes a difference and if you need the extra juice it will help you.
However, the amount of difference depends on your use.
If I am using Snapdragon Battery Guru should I deactivate Power Saver? Is the Power Saver a better/worse solution or a complementary one for optimising battery life?

Theoretically they should work together fine because Battery Guru studies what you do with your phone so that it can figure out what to prioritize and what to shut down - it adapts so it should adapt to the power saver situation. Underclocking the cpu shouldn't change what services it adjusts because you're still doing all the same things.
Battery Guru just finished "learning" on my phone yesterday so I don't know how good it is. But I lost 40% overnight for some reason which has never happened before. It's probably still adapting. Life seems to be better during use...
The comment above about the OS being adaptive is also very true, my first few charge cycles were dismal but they got better within a week (without power saver etc.)

Ya I'm using Juice Defender Plus on my HTC one running 4.1.2 for a few months now and I'm not sure if it's making too much of difference. Are you finding Battery Curu pretty decent?
I turned it off on my wife's HTC One. It was disabling data/wifi after several minutes inactivity, which caused FB Messenger to freak out and stay awake, which caused the battery to drain faster than if the data was just left on.

Sorry still to early to tell really, it's learning period ended yesterday so it'll take time for GSam to find the new average usage. But again it SEEMS to have improved drain during use. I'm really not sure what the drain last night was but if it happens again tonight the app is gone...

I used to have a higher drain, but after some research, I found out using betterbatterystats that google maps was waking up the phone often and preventing sleep. I corrected this by disabling "report from this device" in google maps settings.
Before this, I experienced similar battery drain with power saver on.
From experience, it's best to determine phone sleep time and app battery usage, and correct this to achieve the best life.
I'm currently able to get two days with light usage without power saver!

I changed my mind, I'm consistently losing 40% per night after Battery Guru activated. I can't confirm that this app is the problem, but it's never happened before and I haven't changed anything but adding the app. Maybe just me experience though.

I've uninstalled BatteryGuru for the same reason
I'm relatively certain that for many people this is super old news, but I'd like to share this anyway just in case it helps anyone (and a bit because I'm just so impressed by how it works )
I've tried a few different power saving strategies on this phone and have been disappointed with all, including just keeping power saver on all the time. I would always lose 20-40% overnight no matter what I did. I should also clarify that it is not acceptable for me to just disable a bunch of things to get that drain under control. So one day I turned on power saver (everything checked off) and just turned off wifi, and I've been doing it ever since because now I only lose 5-10% over night maybe a strange thing to be excited about considering my other devices lose as little as 1% in that time with nothing turned off, but everything's relative.
I think now I'll try keeping wifi off and power saver on throughout the day and see what I get. Though I'm not sure I like the thought of data being turned off during the day when the screen isn't on...
For me at least this is the single best battery saving thing I've ever done on my One.
Sent from my HTC One using xda app-developers app
What you mean by saying that you "turned on power saver (everything checked off)"? What Power Saver does if everything is checked off? I suppose like that it actually doing nothing. If you uncheck everything and turn it on isn't the same as turning Power Saver off?
My XT1092, recently got updated to Lollipop i.e. Android 5.0
Two of my battery runs, starting from 100% full charge came down to like 5% and the phone shut down automatically as if it was 0%
Also on a side note, i did not put any mode on the battery saver mode for those two runs.
Now to test it, i kept my battery saver to start at 5% but i am not sure if it will run at 5% or just shut down
Anyone got an idea/solution for this issue ??
P.S. Even Motorola care chat, does not have an answer, all they said is to keep my phone in safe mode for a day and check it out....
Mine just did this the other day. When I pressed the power button it showed the battery with a little red fill and a huge yellow triangle with an exclamation mark in it. Also happened last night.
I have also had the same issue xt1092 and on lollipop.
well...
yea man, so the thing is motorola support said that, keep ur phone in safe mode for a day and recheck the issue...
so idk... :/
i am checking my battery use and for now i have kept my battery saver on 5% so i hope it starts on battery saver itself.. rather than shutting down...
My XT1095 does the same thing. Really annoying! Its really lying to you about how much battery is left if its going to do that. I just know that if i'm going below 10% i better run to find a charger ASAP!

I've never let my battery get that low honestly, but...
Keep in mind that your battery percentage is completely an estimate. Battery capacity is measured in mAh, but there's no way to measure the current charge capacity in mAh of a battery. The only way to do so would be to run all of the power out of the battery and record the power over time, but then you'd have a dead battery. As a result, the system estimates your remaining battery capacity as a percentage based on the current voltage of the battery. But that can be different depending upon how quickly you've drained the battery and other factors.
So, Android has methods built-in which automatically calibrate the battery, but they only work properly if you fully charge and discharge your device on a regular basis. A battery starts off weak, then it gains strength after a few charging cycles, finally over time it peaks and then begins to taper off as far as battery life goes.
You've likely not taken your device to 0% for a while. The android solution is to fully discharge and recharge your battery a few times to allow it to recalibrate. Slow charging is the best for recalibration. Plug it into a computer for 500mAh charging rather than using a charger. Chargers can charge quicker(1.5A) but do not allow the device to calibrate as well due to the high amperage.
So, just use your device and let it drain fully, and charge fully on a computer USB port and it should recalibrate itself.

While it does help the calibration, it's very bad for your battery to do this deep discharge multiple times.

Sometimes you don't have a choice about letting battery drain get that far.
But regardless, its most definitely an issue with lollipop. Uncountable android devices, and this is the first time I've ever experienced this issue. Happens religiously at 5%. So its never happened before on any device I've used, including this moto x pure on KitKat, and it always happens at 5%.
If it were a true calibration issue, one would think it'd happen at different percentages. However I'm certain this is a bug.

I understand that you don't always have a choice, I just meant that I have no insight as to the possible bug since I've never experienced it. And to clarify, it's not really a "calibration" issue, it's a matter of there is no way to accurately measure the charge of the battery.
Honestly, Google could have even implemented this intentionally in order to prevent damage to the battery from a deep discharge.

But android has been completely accurate in the past. Right down to 1 single percent.
And there's no way google implemented this as a safety feature. If they were legitimately trying to do this, they'd just have the battery monitor read less than actual capacity as to not confuse the operator.
As well as they have what they believed to be a big feature, "battery saver" which has the option to activate at 5%. So them killing your phone at 5% intentionally doesn't hold water.

No it hasn't. It may not have shut down until after it read 1%, but it has not been accurate because there is no accurate way to measure the current charge of a battery.
http://batteryuniversity.com/learn/article/how_to_measure_state_of_charge
The fact that it consistently shuts down at 5% does seem like a bug, but it's a very odd bug since it seems like there would have to be some code to specifically tell the phone to shut down.

Every android device I've owned, probably 12, including the 3 still in service with me (moto x before lollipop, nexus 7, nexus 4) all have accurate battery meters right down to 1%. Now are they adjusting on the fly and lowering/raising battery percent to accurately match calculations? Probably. But it adjusts to where the battery meter will read down to the very last percent. No surprises.
The whole point of this thread us that some moto x pures are shutting down at 5%. Maybe the battery really is at 0%, maybe its at 5 or 10%, but its a "bug" that the phone is shutting off at 5%. Its rather a flaw in on the fly calculations where its not accurately adjusting at lower percentages, or a software flaw. But it's a bug either way. That's the complaint here.

Table 2 provides details as to why what I said is correct. A 50% discharge will not degrade to 70% capacity for 3-4x as many cycles as a 100% discharge. That amounts to up to double the useful life of the battery assuming your usage stays the same.

Mobile device batteries are designed to be "fully" depleted. They are software controlled. You will never discharge a properly controlled battery 100%. This is why your device still has power to turn on and tell you that the battery is too low to turn on.
There are always exceptions to the rule. However, mainstream devices will almost always keep the battery at a safe level.
You cannot use a single chart on all lithium ion batteries. In fact, every one is different due to chemical and annode/cathode changes. This is why every battery has its own MDS for shipping purposes.
The small changes to batteries cause them to react differently to different usage patterns. When designing a battery these reaction patterns are supposed to be accounted for in the battery calibration.
A key engineering principal: a device should never be capable of destroying itself. Full discharge is normal operation for most devices.
I just bought my Z3C a couple of days ago. First thing I did was charge it fully and then I started using it. It went from 100 to 0% in about 21 hours. During that time a SIM card was inserted only during the last couple of hours, but I did use the phone fairly often. The attached thumbnails show the details.
I did notice that it almost loses no charge in standby. But today I noticed an increased decline during screen on time after standby time. See last screenshot attached.
I expected more from this battery based on reviews and Sony's claims. Is this normal or is my battery faulty? While some here report similar numbers, others seems to get a lot more out of their batteries.

You shouldn't expect more from this battery based on reviews, you should just look at what some people got out of their phones.
Give the phone some time to settle in. And don't forget that it's almost summer for us now, more sun means using the screen at a higher brightness so that will also have some impact on your battery life.
Look what kind of useless apps are running in the background and stop them and don't worry about the estimate, it really doesn't mean much. Right now my estimate is 9 days, because I barely touched my phone.
I really don't believe in such a thing as faulty battery. Charge your phone, restart it and see how it reacts then.
Is Stamina mode enabled? If not, then what you have is typical. Getting a full day out of one charge is about all you can expect from a smartphone without some form of battery saving measures enabled.

With moderate usage, you should generally expect just about 2 full days of battery life from this phone. And that is with Stamina mode enabled to help the phone sleep when the screen is off. However, this is not accounting for any extreme measures some people take to extend their battery life (e.g. disabling background data/sync). Once you remove these features, you're no longer using the smartphone as it was intended, so it's not a fair comparison.
I can easily get 2 days out of my Z3C before I think about charging it. And I've never used Stamina Mode.
I guess I could install some app to monitor battery usage and stats but I'm not that bothered tbh.
We all manage a variation on the smartphone thing, in terms of data, wifi, gaming, emails, browsing, texts, calls, etc, and its slightly different, in terms of use, from one user to another.
I'd echo the sentiments of another user who said give your battery time to settle in. Give it a full charge, discharge cycle a couple of times, and don't worry too much about it!
Peace.
Thanks for your feedback, guys. I'm currently fully charging and discharging my battery. Several cycles complete.
The best result I've gotten so far is a little under two days with moderate usage and thorough measures to increase battery life. I turn on airplane mode when I go to sleep. Stamina mode is also enabled, but only the reduced performance part. I'm also using 2battery, which turns off WiFi and data when phone is in standby, and turns them back on briefly every 15 minutes. (While I agree that turning off data connections defeats the purpose of a smartphone, I also believe that there is no need for a constant connection when I'm not using my phone. 2battery achieves that. Although I must say it doesn't seem to kick in a lot on lollipop.)
So despite these measures my battery seems weak compared to yours. Anyway, I'll be taking your advice and I'll give it some more time.

I have like never used Stamina mode, try out these apps:
https://play.google.com/store/apps/details?id=com.rootuninstaller.batrsaver
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats
You need to be rooted tho (Which shouldn't be a problem)
Are you using GPS or is it always on?
Your battery is fine. You probably lost some standby life when you put a SIM in it, as that would cause your cell radios to begin seeking your carrier's towers.
Do activate Stamina mode if you haven't already done so.

Thanks for the pointers! I have Better Battery Stats, and will give the other two a go. Sounds like DS Battery Saver goes beyond 2Battery, which just manages data and wifi. It can also kill apps, but I suppose you use Greenify for that?
I am indeed rooted. GPS is always on as far as I know. Haven't really paid attention to it. Why do you ask? Does that consume a lot of power?

Well yeah of course GPS uses a lot, especially when you don't use it, it's just wasted energy so to speak.
Greenify lets apps go to sleep earlier/faster so that they can cause less wakelocks.
With Greenify and DS BS I don't need Stamina mode and many of us are even wondering if Stamina is working most of the times, these two apps I'm certain that they work.

Well, I've been keeping an eye on it for the past week, and I seem to be losing next to no charge when screen is off. My phone is in deep sleep over 75% of the time. (According to Better Battery Stats)
I do seem to be losing 1% charge for every 3 minutes or so while my screen is on. Is that normal? We're not talking gaming or anything demanding, just some browsing and messaging.

I think the best way to measure if it's correct or not, to for example put some movies on your phone and let them play constantly, see how long your phone can manage.
You should get at least 6 hours of on screen time using that method
It's too late to say this, but after getting a new battery/phone you should always drain it fully and then fully charge the battery so that the battery has a proper charge (it saves a lot of battery capacity and battery life)

Good that it's too late, because it's incorrect. This suggestion dates back to the days of NiCd batteries which had "memory effect". Li-Ion batteries found in modern devices for at least the last several years and definitely since the beginning of Android don't have this effect, but have something else - when you drain the battery completely, you cause damage to the battery cells, and it can withstand only a few of these full-draining cycles before losing significant part of its charge capacity. This is why both laptops and phones have protective measures to turn off the phone completely before the battery reaches a dangerous drained state. And as the batteries go bad and their "low percentage" scale becomes unreliable (not able to sustain operation currents with low charge), these protective mechanisms can fire too late - which in turn can cause storage corruption to occur, if the power is lost gradually and not abruptly during operation.
To another poster that doesn't believe in faulty batteries - he better should. Batteries go bad with time and charge-discharge cycles, they're harmed by complete discharge, and can go bad in several other ways. However, I wouldn't expect a battery to start its life damaged - quality control of the manufacturer should prevent this.
My results for reference - I have ~2-3 hours a day SOT, 1-2 hours tethering, have several phone calls, messages and mails - and the phone is usually upwards of %50 at the evening. I have to run it through ~4 hours navigation to reduce it to sub-20% towards the end of the day, and actually see no reason why a smartphone should hold any longer - it's routinely recharged every night. The main problem for smartphones, to me, is not surviving till the end of the day.

Thank you for sharing, but that advice is about as outdated and useless as changing your car's oil every 3000 miles. Batteries simply don't work that way anymore and some studies show that battery life is actually reduced when you perform full charge cycles instead of shorter recharges throughout the day.
Edit: looks like someone else best me to it :-/

Actually sorry to break it to you, but you are wrong, Li-ION batteries do have a memory effect, since about 2013, researchers have found that they do have memory effect.

Well, thanks for showing me something new. However, this is a very different effect from NiCD. While in NiCD this effect would prevent the battery from taking a full charge when repeatedly not discharged fully, in the research you've showed there are 2 very important points:
1. What matters is not the discharge, but rather a charge. Charging not fully is a way to trigger this effect. On the other hand, discharging partially (like in NiCD) doesn't trigger it. This point makes the info, while indeed interesting by itself, irrelevant to the current discussion, and keeps your previous suggestion wrong and bad for the battery.
2. If kept charging a bit longer - the battery would still charge fully, though it would take a different amount of time from the expected. For night time charging, when the phone is connected to the charger for several hours more than it's needed to actually regain the charge, I'd guess that most of the time it does the job of filling the battery properly even after an incomplete charging cycle.
[edit]
After reading it again - actually there is a third point that makes your suggestion even much worse than I thought it is:
This memory effect that you've pointed to is triggered by having an incomplete charge followed by a complete discharge. That means, incomplete charge with incomplete discharge don't cause it - a complete discharge is required. And when you receive a new phone, the battery isn't fully charged - so if someone goes by your suggestion:

He would actually be triggering the memory effect you've linked to, on its bad side!
And just for reference, here is a recent article from 2015 that is far less technical, but does a great job of explaining battery behavior in practical terms that average people can understand:
http://www.digitaltrends.com/mobile/expert-advice-on-how-to-avoid-destroying-your-phones-battery/
Hello,
I would like to ask you guys, what apps do you use to save your battery?
Naptime? Anything else?
Nothing... I don't need to install anything to save battery. That being said, I USED to do this with apps like Greenify on my Galaxy Note 3 (so like 9-10 years ago). But I had stopped doing that a while back as doing so had only lead to even less battery life lol.
to be honest, the best battery saver is to uninstall the native Facebook application from your phone. it eats up battery like anything. you will see a noticeable improvement on your daily battery performance.
I've tried naptime and I've not really noticed a huge difference, at least in repeatable conditions, i.e. overnight. Same with Galaxy max Hz, although i like the additional controls that the latter gives
Love Bixby routines to switch to 2G when at home or activate batter saver when sleeping and not charging. Rly good stuff.
I don't use anything to limit battery consumption, but I do use Accubattery to set an alert when my charge reaches 75%. Reducing depth of charge and not charging to full 100% is a way to reduce battery wear, so ultimately that extends battery life.

I kind of do something similar. I've got a Bixby Routine to shut off the smart plug that the charger is plugged into when the Battery percent reaches 80. Unfortunately, Bixby routines isn't very reliable.

I use Accubattery as well to monitor temp and charging.
If you use any power management especially 3rd party ones it can cause erratic behavior and may create conflicts that use more power than they save.
I deal with power hogs directly by either adjusting settings, disabling them or firewall blocking them.
Certain apps like Brave, Gmaps I manually close out when done or will they continue to poll the internet in the background and use power.

You can just turn off all notification and disable(deep sleep) in Background usage limits.
I’ve been using AccuBattery with IFTTT to shut off a smart plug at 75% for several years now to extend my phone’s battery life. This has been very reliable, it runs every morning before I wake up.

what do you mean disable? add facebook to deep sleep list? I noticed it's not working, even if I but it in deep sleep list I still get notifications. And do rly disabling notifications for facebook app improves battery? any source about that?

No, no. The first person essentially said to uninstall that crummy, built-in Facebook app and then to put some apps that you don't need notifications for into deep sleep mode. The second person mentioned the same thing with different wording.
