[Q] HTC Desire Battery life

I've been using HTC Desire s just for 1 week, it's good device but can't use a day after full change morning. I hate the battery life iphone but it is worse. Do you know how to get the battery life better this HTC Desire s ?
I've done 2 things like below.
1. 10 Tips for saving HTC Desire
2. Once full charge after battery dead(100% consumption)
Any better idea ? Thanks in advance.
I can't put the link for gadget 10 tips link due to 1st posting...

Same to me. 30 hours is max. This is not very good....

I also have the same as if I leave my desire S in stand by for 6 hours it loss 50% of charging and I sure that everything are closed (Wi Fi , Bluetooth , GPS , data connection , Application) so pls can anyone advise if this is special problem on my phone or it's generally in all Desire S

I find the battery quite good actually.... I normally charge it over night and have at least 25% left, normally towards 50 depending on how much angry birds i played
I have WiFi or 3g enabled, no gps or bt

Perhaps you can install battery monitor to find the cause...

I'm getting around 30 hours before my nerve goes and I charge it up again at about 25%, but I'm still using the phone quite a bit more than the dumb-phones I've had in the past.
Check: Settings > About phone > Battery > Battery use
Essential apps:
Battery Monitor Widget
Power Monitor Widget
Screen Filter
I have the screen set to auto brightness, but use Screen Filter to reduce the overall brightness to (say) 50% outdoors, 35% indoors, and 25% in the evening.
I find the biggest drain on the battery is the display, but maybe that's because I've reduced a lot of the syncing.
In "Accounts & sync", I've disabled syncing for most things, especially HTC Sense; Weather widget updates every 3 hours, other things every hour or so.
WiFi is usually off, though even when it's on, it doesn't drain the battery much.
I get the worst battery drain when playing games or watching video, especially with the brightness turned up.
GPS is enabled, but rarely in use. 3G coverage near me is poor, so I'm usually on 2G only.

[ duplicate post got created somehow when editing - can admins delete this one? ]

Try these:
-wifi settings advanced setting for sleep after 15mins
-usb debugging on
-cancel auto sync OR sync frequency for all those things that like synching all time
-change email sync (default is every hour)
-change weather update
-turn off gps
-screen sleep quicker
there are some apps which are poorly put together and can drain battery, i had problem with android market fault and had to reinstall it, also 3g watchdog had an issue before
the desire s battery is better than most android phones, certainly one of the best compared to other htc phones so battery life shouldnt be an issue..

I get two days use. I consider myself an average user. Calls, sms and internet browsing.

turn your brightness down Switch off your data when not needed... use task killers? (not sure about task killers for android)

Don't use Screen Filter unless your intention is to reduce glare when using your phone in darkness. It will not save you any power if you are using an LCD display. and

If all you do most of the time is idling, it should last a couple of days.

My experiences:
I always using all features in mobiles such as localisation, 3G, wifi, synchronization always on. I'm doing this because phone is for me/I am not for phone
Some stats on Desire S:
-wifi only(mobile network off) 60 min of video, 10 mins voice calls, few text, few emails, few webpages 50% screen brightness
result: 27 hours
-wifi off(mobile network on) 60 min of video, 10 mins voice calls, few text, few emails, few webpages, 50% screen brightness
result: 22 hours!!!
Cmon HTC, this are very bad stat!
Anyone know is that good stats? Please don't tell me to switch off this and that...If We will be thinking in this way maybe we just put mobile on air plane mode, set birightness to 20% and then We will get around 40 hours.
Do You think, that custom roms can help with it?

Just curious. Did any of you do the battery calibration thingy?

Of course I did. I always doing calibration even if now is not necessary...

I have WiFi, BlueTooth, 3G on all the time. Sync on and the device is in background alone collection app. 3MB of data.
If I don't use the phone, then it uses app. 15-20% of battery a day.
I can use the phone app. 5-6 hours a day for browsing, install programs etc.
I thing that is a full days use.
I have turned off auto brightness, as I don't think it is working. In normal day light I set the light to 50% which is nice for the eyes. (Auto mode goes to almost 100% all the time, which uses more power.)

[GUIDE] Battery Management for noobs

Hey guys,
So after many months with the XT720 and alot of flashing and trying to get the most out of my battery, i've come up with a few conclusions about battery life in general and how to extend it. I thought I'd share here. This is mostly aimed at people who are new to android and have not experimented like some of the more advanced users we have on this forum. Hope you find this helpful and please feel free to make additions.
General Battery Info
The XT720 was my first android phone, and I came from a long line of typical nokia phones whose batteries would last for ages. I had no idea the kind of power an android device would use. When I started out using it, i was surprised at how quickly the battery would die. You'd think with advancing software we'd have better batteries but sadly batteries are lagging behind in technology. Generally speaking you can expect the following battery life from your XT720.
Heavy use: 10-14 hours
Moderate use: 16-20 hours
Light use: 1 day - 1 day 12 hrs.
Note: New batteries improve with each charge cycle. It is recommended to go through a few complete charge cycles when you buy a new phone. After that, complete discharges are not recommended and its smart to start charging your phone when it hits the 20-25% mark.
How to improve battery life
1: Battery Calibration
If you've ever flashed a new ROM, you must have noticed a sharp decline in battery performance. This is partly due to old battery statistics left behind from your old ROM. Android is a smart OS and collects information over time. The more you use it, the more accurate it gets. In the same way it collects information from your battery usage and reports your battery percentages according to that. When you flash a new ROM, sometimes android thinks that your battery is 100% when its really lower than that and that causes relative reduced battery performance. To deal with that it is recommended that you use a nifty free app called Battery Calibration from the android market. What this does it removes the old battery stats and allows your new ROM to create its own battery stats. Charge your battery to full, use the battery calibration. Drain once till phone turns off by itself and charge to full again. You will notice a sharp increase in battery life.
2. Battery Managment
We all know that android has its own battery management built in but it usually doesnt give complete information about the phone. For that you need to dive deeper into the settings. Usually if you experience battery drain its because of a rogue app and believe it or not some common apps you wont think off drain unnecessary battery. To see your complete Battery Stats input this code into the dialer.
Code:
*#*#4636#*#*
This will take you to a bunch of options. What you're interested in is Battery History. When you tap that it will show you two drop down menu's.
1) Other Usage
2) Since last unplugged
Other usage shows you how long your phone has been running and how long it has been asleep. Also shows you how long your wifi has been on and running and how long your screen has been on. It is important to see how long your phone has been running. For example if your phone has an uptime of 20 hours and its been running 5 hours out of that. Your run time is 25%. Which is very good. Sometimes an app can run even when your phone screen is off. This will represent a longer run time even when you have your phone lying on a desk or something. See this setting and correlate with the amount you have used your phone. Does it seem normal? If no then use the first drop down menu and select
Partial Wake:
Partial wake is basically, any app which takes your phone out of sleep mode to use the CPU even when youre screen is off. These are apps which need to sync or use the phone resources. In this you will see a list of apps and how much they have caused a partial wake lock. See anything unsual? For me one app that caused unsual drainage was latitute. Yes, i had simply signed into it and i didnt know it was updating my location every 5 minutes. Extreme battery drain for me even when my phone was idle. See which app was draining your battery and either tweak the settings or remove altogether.
GPS, Sensors, CPU:
You can also see these in the first drop down menu. Certain apps like screeble use the sensors alot, and hence cause drain. Obviously games, camera, will stress the CPU. See if anything is causing drain in that and adjust accordingly.
Miscellaneous Information
After you have dealt with rogue apps that you don't use that drain youre battery your battery life will depend on how you use your phone. But hopefull these tips will help you with increasing your battery life. I do have some more information on different settings and supposed battery saving applications.
Autosync: When you enable auto sync, you allow google and other accounts to sync on a regular basis. This is important for people who need to use push email etc. It does not drain battery IF you tweak what you need synced. In google for example you can have your contacts, calendar, google+, google reader, gmail all to sync by default. If you just need email, please untick the rest. This will help you save battery life. Increase your update times for facebook and google+ if you dont recieve many updates all the time or turn them off altogether. If you have many services syncing at the same time you will get battery drain.
Wifi Sleep Policy: This is sort of a hidden menu. If you go into wireless & networks >> Wifi settings >> settings key >> advanced >> wifi sleep policy. This has three settings. Never close down wifi, never close when charging, or close with screen off. If you choose never your wifi will always be on, which will in turn crunch the **** out of your battery. If you use it off with screen off, remember it takes about 5 minutes to turn the wifi off. I personally use the never with plugged in. Its an intermediate. So when im plugged in wifi always stays on and when im not it follows the screen off protocol.
Wifi Vs Mobile Data: Having mobile data on all the time, does not drain battery. The only time the battery gets drained is when the data connection is active i.e you have many apps on autosync youll see your battery going down. If you arent doing anything and your phone is connected to Edge or 3G your battery will drain regularly. 2G networks drain less than 3G keep that in mind. If you are actively using your connection, wifi will take less battery because speeds are faster and you will be using it for a little time. Also your signal strength has alot of effect on battery. If you have crappy 3G signals your radio will actively be searching for a connection the same goes for wifi. That is important to keep in mind.
Control Background data: By selecting this option you can allow or disallow apps to connect to data without any permission. Some apps require this like the android market. If you uncheck this apps wont be able to sync automatically in the background.
Milestone Overclocking: This is fairly obvious. The higher you overclock with higher vsel the more battery drain you will have. Some use set cpu with profiles but I found that if i set the setcpu too low while idle It takes time for the cpu to charge up when i recieve a call or turn the screen on. Ringtones lag etc etc. I let android do my CPU management and its fine. and comfortable setting would be 850 MHZ, 56 vsel but you can change according to your phone usage.
Juice Defender/ Screebl / Task killers:
In my personal experience with juice defender ultimate I found that with the above precautions juice defender didnt make much of a difference and actually used more battery. First off theres an extra process going on in the back. Second activating and deactivating the connection everytime the screen goes off uses more juice because your radio has to search for the signal hundreds of times as compared to not having it in the first place. Screebl is good if you dont want your screen to annoyingly turn off while youre doing something but it surely doesnt save battery life. Task killers are a no no for android. They kill tasks which start up anyways, its better to use autokiller memory optimizer which tweaks androids internal memory settings and allows for more free ram without killing processes without reason.
System Apps:
Some system apps run uselessly in the background specially with stock ROM's this is called bloatware. Remove all unused system apps with titanium backup to stop them from running in the background for no reason at all.
A final word
Finally after all this tweaking, just use your phone as normal. Dont worry about the battery all the time checking how much its drained, itll mess your head up and make you enjoy your phone less. Battery temperature also changes battery life. Keep your phone out of the sun or in hot places.

Thanks, good article.

Very detailed and useful

Thanks for this interessting article!
Could you make a list of the bloatware that can be safely removed?

I figured this would just list all the usual stuff I've heard. I'm glad to say I was wrong! A bunch of useful info here I now plan to put to use. Many thanks
Might want to mention the display being the biggest drain of battery on this phone. Setting it to automatic brightness or lower will increase battery life. I love the screen at full brightness so I don't really follow that, but for those looking to squeeze some extra time and don't mind less brightness...

Thanks guys, glad you people found it useful.

Yes! Can't believe I missed that one out. In the start id use the lowest brightness setting, which would be fine indoors. But outside it was impossible to see the phone because of its insanely reflective glass. Since we have an ambient light sensor I use it on automatic and it does a good job. Full bright strains my eyes abit thats why I dont keep it on full bright So for people really wanting to save the juice you can keep your brightness on the lowest level. Also when you take the phone out of your pocket and use it, its better to put the phone to sleep with the power button than let it timeout by itself. Those 10-15 seconds for each time you use phone count towards many minutes of unused display time in the end and does make a difference.

This is a very gd post with lots o useful info!! ok i have a qn, is using the phone a lot while the charging good for the battery? And if u let the battery charge even though its already 100 percent for an hour good? srry if it is noob qn...

1. Using your phone while charging does not affect your battery life, and is neither good nor bad. It is perfectly normal to use your phone while charging and is sometimes recommended while doing battery intensive tasks for example navigating while driving, wifi tethering, playing memory intensive games and finally outputing video through HDMI.
2. Overcharging was a phenomenom is older lithium ion battery. New batteries have bypass circuits. So when your phone reaches complete charge, it does not charge any further. So you should not be worried about overcharging your XT720.
Hope this helps.

Excelent article and good quality info. Thanks and best regards!

awesome article! Great information. Thanks a lot for putting that together. I have already started using a few of the tips mentioned.

Verizon SGS3 battery life?

Does the Verizon version of the Galaxy S III have worse battery life than the other carriers' versions. So far I have had pretty poor battery life with my phone. I have had it since Friday the 6th. Since then I have gone through multiple charge and discharge cycles. I've been averaging about 8 - 10 hours of life, with about 2 to 2.5 hours of screen time. I use the phone for about an hour of browsing the web in the morning, on the train to work, then another hour on the way back. While I am at work I turn off the mobile data and WiFi. I basically only use it to check text messages. In that time It'll still drain about 5 to 10 percent per hour. I have already reset my phone to factory settings. It also seems to act normally up till about 70 percent, then it starts to drop really fast. I want to maybe get another battery from the store, but as the phone hasn't even been released yet I'm not sure what my luck would be. Has anyone else been having better results if not similar problems? Does this seem like an issue that could be solved by replacing the batter, or would a replacement new phone be needed to fix this?

Replacement battery
It seems that Verizon cannot give out any replacements until the in store launch on Thursday at the earliest.

AT&T seems to be pretty horrible. Have you tried CPU Sleeper by eugene373?

I have not tried that, but I have tired standard things such as Juice Defender Ultimate and what not. The biggest thing to me is that even when I turn off mobile data and wifi, it still starts to drain rapidly after about 70 percent. I will be at about 70 percent at 4:00 pm and by 7:00 i'll be at 10 percent with 30 min usage during that time frame, with only on LTE during that 30 minutes.

I have had 4G on all the time, and unplug it at 6am and it has lasted me quite easily until 10-11pm (down to about 10%). I have all data sync on, send approx 100 text a day, play a few games daily, read forums, Google reader, stream music and tethering as well.
I would contact Verizon support. It may be just as simple as a new battery. As of right now I still have 41% left and that will last me the night.
edit: I am also not using any battery saving apps like juice defender or turn off mobile networks either.

Ya, I did and they said I could come in and get a new battery tomorrow, so we will see how much that helps. I just hope I don't have to get a replacement phone because more or less likely the new one will be refurbished. Plus I hate wasting screen covers.

If it is under 30 days they will usually replace with a new phone. That has been in my experience. this happened with my Fascinate when I first got it.

Is it worth trying to just get a new battery first. Or should I just go straight for the phone replacement?

Coming from the rezound, 2-2.5 hours is amazing battery life!
Honestly, it may just be the battery. Try that first, and if it still fails, then return the device. Just remember that Verizon only does 1 free battery during the warranty period.

you guys need to debloat...the problem is the 100 apps that verizon preinstalled has many backgorund services running.
After debloating I went 27hrs w/ 3hrs screen on, 2hrs talk time, and still had 17% percent battery left...like a BOSS!!!

i'm amazed at verizon's battery life. i have an AT&T one and after 6 hours of use and 2 hrs screen time, mine was at 53%. my girlfriends was at 53% with 13 hours of use and 1 hrs 14 min screen time. i cant figure out why.

My room mate has one from AT&T and he can get about 20 hours till 20 percent, with 4 hours of screen time. Not to mention making phone calls and what ever else he does on it during the day. My battery life seems normal in the morning. The only reason I want to get it replaced is that at about 70 percent it'll start dropping rapidly even if I don't touch it during that time.

take a min and go through all the settings in the phone that you think might effect battery life and if you don't use it that often, shut it off. also, disable the apps you don't want/use in application manager. i have about 24 apps frozen, smart stay off, motion off, brightness at 1/3, email sync set to manual, location services off, facebook sync and notifications off, bluetooth off, wifi off, menu/back lights off, heptic feedback off. i can't remember what else but yesterday i unplugged it at 430am with normal use throughout the day (numerous email, facebook, play store use, texting, hr worth of phone call) and this morning at 6am i was at 9% battery left (this was in 4G). Id say that is pretty good! i am very pleased with the battery life with this phone! everyones battery life is going to be different with all the combinations of settings that can be different.

Which apps, did you freeze? Also I just got the new battery so I'll give it a day or so and see what happens.

Is this normal? My screen on time is about 1 hr and 20 min... Not sure if this is good or bad. Yesterday I only got about 6 hrs with around 2 hrs of screen on time.

I am not rooted either as of now, I am kind of waiting to see if they find a bootloader work around. I disabled most of those apps, plus I picked up a new battery around mid day. The only other thing I have noticed is that the phone oddly seems to charge better while on then off, where as my DINC was the complete opposite.

Share with others tricks used to extend battery life.
Tricks known to me:
1.Reduce your Screen Brightness
Display uses about 5-80% of battery usually. Reducing the brightness helps to increase the battery life a lot. To do so goto Settings->Display->Brightness
- Automatic brightness is good but lead to higher consumption of battery. Close brightness automatic and set brightness low.
2.Disable Wi-Fi, Bluetooth, GPS, NFC
Even though Wi-Fi, GPS and Bluetooth are designed for low-power consumption, they drain the battery. Most of the 2012 android devices have a unique feature known as NFC (Near Field Communion) such as i9070p. This feature enables a sensor field around the handset and is used for sharing. This also drains the battery unnecessarily. So it’s better to turn off the Wi-Fi, Bluetooth and NFCs when it’s not in use.
- Deactivate Wi-Fi when not needed
- If you do not use the Bluetooth function, disable it.
- If you do not use the NFC function, disable it.
- If you do not surf the internet stop any data connection
- As long as you do not use GPS and/or location services, close them.
3. Prefer Wi-Fi rather than GPRS
It may be weird that the GPRS consumes more power when compared to Wi-Fi. For example, Wi-Fi consumes 5% charge; the GPRS connection consumes 15% charge. This may not be seen while viewing websites but in case of watching a video in YouTube or making a call in a VoIP service, it drains the battery at a rapid rate. So it’s better to use Wi-Fi to watch videos or making calls.
.- Wi-Fi network consumes less than 3G connection, it is recommended to use Wi-Fi
4. Avoid Live Wallpaper
The live wallpaper drains the battery to a considerable rate. So it’s better to use static wallpapers rather than the live wallpaper.Also use images which contain black color because the LED screens use less power to display black than displaying white. Doing this helps to increase the battery life up to 10%.
-Use a dark background, save battery. Light backgrounds need more battery.
5.Disable Data traffic
Many applications use data traffic in the background letting this phone to sleep. Some of the apps which use the background data traffic are GMail, Whatsapp, Facebook, Viber, Twitter, LinkedIn, Google Play, etc. These apps checks for the updates and for incoming messages all time. So it’s better to disable the background data traffic.
- Network 2G network consumes less than , it is recommended to use 2G connection
- If you do not surf the internet stop any data connection.
6. Disable Auto-Sync
This option comes under the background data traffic. This feature checks for the mail all the time. Which means you will be able to get the mail in your handset as soon as the mail arrives. But this service uses a considerable amount of battery
- Upload and sync only on Wi-Fi. Or stop sync on all accounts.
7.Do not use more widgets
- The more the widgets, more the RAM, more the battery will be drained.
- Dump the widgets
8.Disable Adobe Flash
Adobe Flash enables to watch videos in websites but it drains the battery a lot. The main reason why adobe discontinued its service from android 4.1 is this battery problem.
9.Turn OFF vibrations
The smartphones makes use of some energy to make a vibration, but when “Vibration on Key press” is enabled, while typing a word the phone produces more number of vibrations. It consumes more battery. So it’s better to disable this feature in the keyboard settings.
- Vibration consume energy. A low intensity vibration or even disable as reduce battery consumption.
- Disable Haptic feedback.
10. Power saving mode
If you use your device constantly throughout the day, you may want to consider using your device’s power saving mode. In fact, many of the tips suggested in this post are implemented in most devices’ power saving mode. For instance, power saving mode usually limits CPU use, reduces screen brightness, deactivates haptic feedback, disables data network when the screen is asleep, and lowers the brightness level of the browser’s background color.
The generally recommended advice is to disable power saving mode when you intend to use your phone’s smartphone features; otherwise, turning power saving off can help you stretch your battery life further. So, for instance, you might want to disable power saving mode if you plan to play games on your phone, or else you could experience lag or jitter.
11. Do not try to overcharge
Normally the smartphone charges up in 1-2 hours. But if you charge it throughout the day, it lowers the life-time of the battery. Check the condition of the battery often to have a good battery life.
12.Reduce screen timeout
- Screen timeout should be as low as when not using this device to enter sleep mode. (15s)
- Sensitive buttons should be as little heated. (1,5s)
13. Uninstall unnecessary apps
You can never be too sure what's running itself in the background, what with all the multi-tasking, self-uploading, auto-replicating features in today's modern Android apps, so at least minimise the chances of something randomly hoovering up all your battery by constantly trying to connect to some non-existent server, by deleting any unused or old apps. Some apps are resource-intensive — either by nature (as in the case of games) or by developer incompetence or negligence (as in the case of poorly written apps).
14.Never leave applications open
- Never leave applications open in the background for long time. Set the limit to 1 or 2
15.To root or not
Rooting may have drawbacks but the benefits far outweigh them. One attractive advantage of rooting is that of possibly improving your device’s battery life.
16. Debloating
Rooting itself won’t lengthen your battery life. Rooting merely opens the gates to your device’s restricted partitions and directories. With such restriction gone, you can remove useless apps (e.g., bloatware from carriers or OEMs), especially those that run as background services, wasting away precious battery power.
17.CPU underclocking
With root access on your device, you can also install apps that can improve your system’s performance. A CPU controller app, for instance. Three names instantly spring to mind: SetCPU for Root Users, No-frills CPU Control, and CPU Tuner.
Apps like these essentially allow you to tweak the CPU settings on your device. You can set the CPU frequency to stay at the lowest (and, as a result, use up the least power but sacrifice device performance) or to stretch the CPU to its maximum limits (resulting in better and faster performance, but at the price of heat, quick battery drain, and potential system instability).
Be careful when using such apps. There are risks involved; for example, your device could behave erratically when its CPU clock is set higher than usual.
18. Custom kernels and ROMS
As we have an unlocked bootloader and custom recovery in the process of rooting. Many custom kernels and custom ROMs. Feel free to look around XDA for guides on how to flash custom kernels or custom ROMs to your particular device.
Battery life is one of the biggest issues in the Samsung Galaxy S GT-i9070 Advance. Take your SIM card out, turn off Wi-Fi and never touch it and it'll sit there happily, lasting for a whole week on one charge. But try to use it for anything "smart" and, well, that's where the problems start.
...and keep it cool
Batteries work best in cooler temperatures, with prolonged warm periods gradually lowering their efficiency over time. Putting your phone in a looser pocket might help, or perhaps just gently fanning it while it charges. That might not be the best use of your working day, but at least you'll still be able to get on Twitter on the train home.
YouTube Video:
http://youtu.be/shApI37Tw3w​
The two attached images show the effect of these methods.16 hours with only 2G/3G connection for 1 hour, listen to music 15 minutes, talking on the phone 12 minutes, 10 messages, 1 hour and 40 minutes gaming and others. I left with 22% battery. To me now is night, which means the phone will remain at rest for several hours, and the battery life will reach one day to several hours.

Without a data connection active, our devices are basically 2G network. 2G connectivity is needed for calls, messages, etc.. Theoretically should consume less than a Wi-Fi network.
I may be wrong, waiting for other opinions. Thanks!

You have got a few wrong..
I do not respond to tech support via PM

It is my understanding that:
- If you are downloading//uploading data, 3G consumes more battery than WIFI (upload also consumes more than download)
- Idle: WIFI consumes more battery than 3G
Always a good idea to disable Haptic feedback aswell.

Keeping the phone always on Power saving mode is a good idea ?
Coz without that my phone battery wont last any long! in power saving it goes approx 15 hours including around 7 hours of deep sleep!

Yeah, why not? Power saving mode do some of the things said by me above and in addition reduces the CPU frequency to 800Mhz.

I'm sorry, but if this is the way you want to use a smart phone, why do you even have one?
Disabling all the connections makes the whole phone quite useless.
My opinion: grab your charger and enjoy or throw your phone out of the window and buy an old school Nokia.

I have to agree with you, disabling syncs or 3G connection absolutely defeats the purpose of having a smartphone. I do all the other stuff to preserve battery, i even have an all-black wallpaper.
You can space out some app syncing (facebook syncs for example and lots of apps can be configured to sync at specific intervals) to get a middle-ground solution.

Thanks .. OP updated ..

I've disabled the following:
Bluetooth (if I need it I switch it on)
Haptic Feedback
GPS
Uninstalled bloatware with Titanium Backup (it helps, bc many unnecessary apps stay online and consumes both memory and power)
Installed Juice Defender Ultimate (auto disables Wi-Fi, BT, mobile data and enables sync at a certain time interval when you don't use the phone)
Use Mobile Data only when Wi-Fi is unavailable
Enable Power Save.
With this setup, I have all day power, and charge the device only when I get home.

Some battery test results

Today did some basic tests to see how the batter compared to a Sony Z Ultra.
Be advised this is not a fair test, the ZU is 2 years old. While the device has been properly maintained and not stressed a lot, its still with a two year old battery.
Screen on ( ZU: 45%, X2: 50% ( brighter then ZU to compensate the battery somewhat )), no activity.
ZU: Lost about 11% in 75 minutes.
X2: Lost about 4% in 75 minutes.
At that rate the devices will last:
ZU: 11h15 minutes
X2: 31h10 minutes
Now this matches up with a review i read where they state that the X2 will last 35 hours with screen on.
The double to triple battery life seems to match up with the reviews i read before. Its powering a bigger screen, higher resolution, has more memory ( 3GB vs 2GB ), and still triple the ( 2 year old ) ZU, despite given a extra handicap with a high screen usage.
Some benches:
AnTuTu:
ZU: 39.900
X2: 49.200
About 25% better benchmark performance. Memory had clearly more bandwidth, faster internal flash, CPU score was a bit of a head breaker. Faster on multithread and float ( probably because of the 64 bit ) but slower in the single core ( pure ) integer performance.
Screens:
If both devices are put next to each other, the ZU its color looks more washed ( grayish ) out compared to the X2. The X2's color are more stronger.
So far its a great ZU replacement.
Things i do not like: The screen has a higher output for everything ( everything looks bigger on the screen ) compared to the ZU where they reduced the rendering size for the font/etc, giving more content on the screen.
This needs a fix somehow ( do not know if this can be changed with a setting or needs a custom rom ).
That is it. Not a lot of time right now.

change dpi in build.prop if you are rooted.
If you are not rooted. run following command inside any terminal app :
- wm density xxx
- reboot device
where xxx is 170 to 400. keep changing it until you find are happy with resolution.

What is the standard DPI on the X2?

400

Good advice, thanks.
Will changing the DPI affect all parts of the UI? For example, will the web browser show more content because the viewport will have been lengthened due to the smaller dot pitch?
I ask because I have installed third party launchers on my device that "simulate" a lower DPI by shrinking the size of text and icons on the home screen, but the magnification of all other apps is left unchanged.

Yes

It did involve a bit more work then what was written above... You need to do a bunch of steps to conclude things to a good end. I made a little mini-guide to help people along:

Hope it helps. Btw: 280 rocks for this device... makes a lot of websites run into desktop made, and Chrome shows tabs. Turns it into more of a mini-pc... and with the big screen its still very readable!

Can you tell us which standard apps are incompatible with the 280DPI setting?
Do the dialer and contacts work? And settings?

So far there seems to be a bug with the navigation bar and landscape. In the sense that the navigation bar shows up but none of the icons show up ( and nothing reacts on the bar ). Not sure if its related to the 280dpi or not.
Some more battery numbers:
3h36min playing Fallout Shelter ( big battery eating game )
4.20min total screen time.
Battery loss: 44%

Works perfect. Took me a hour to figure out those steps ( especially the missing driver! ). *lol*

Today finally did a full charge ( up to 90% ), with still 13% left. So in total been using the X2 from last week Thursday ( full charge to 97% on Thursday night at 20.30, with a small 10% extra charge-up on Saturday when it was connected to my USB for configuring ).
Did some navigation tests:
GPS: Fast lock-on even without A-GPS. Inside 3 meters from the window it found 4 sat's but no lock-on. Closer to the window got 12 sats with 10 in usage.
Cold start outside was done within several seconds, where it took my old HTC HD2 at times 3 or 4 minutes ( Hamburg = big building everywhere blocking the signal too much for my old HD2 its cold start )...
28 min driving with Sygic navigation, with 4G/Phone/GPS on had a battery drop of about 4% ( from 18 to 14% ).
Inside at my work, had GPS + 4G + Phone active during "sleep", drains the battery about 1 a 2% per hour. Probably the GPS trying to get the location while inside, what was draining the battery faster.
Biggest battery eater: Fallout Shelter... this eats battery like candy. I estimate that playing the game for 8 hours will drain the battery from 95% to 5% ... So that is good survivability. If all you do is comic book readying, i estimate that you can easily get 20h+ out of it.

Here are some power usage number over the last 6 days and half.
25/08 21.30: 100%
- Installing some software
- Wifi + Cell on all night
26/08 9.50: 93%
- Call 15 min
- Daily WeChat checks & talks
- Wifi ( useless, no connection ) + 2G + Cell on all day
26/08 17.44: 88%

- Wifi + Cell on all night
27/08 9.22: 83%

- Wifi ( useless, no connection ) + 2G + Cell on all day
27/08 17.23: 74%
- Wifi or 2G + Cell on all day, forgot to write down. Based upon the drop, i probably had 2G and no Wifi on.
28/08 9.22: 71%
- Some WeChat chatting & checking but low activity day
- 2G + Cell on all day
28/08 17.50: 69% << no joke .. only 2% that day??
... big gap, weekend. Forgot to write down numbers.
- Some software installing, playing round, internet usage, ... a bunch of things
- Wifi + Cell on all the time.
31/08: 08:00 ( Forgot to write down but it was in the 40% somewhere )
- GPS navigation for about 30 minutes in the car
- Wifi + 2G + Cell
31/08: 11.47 36%
- Chatting, etc ... you know the routine by now *lol*
- 2G + Cell all day
31/08 18.19: 31%
- 2G + Cell all night
01/08 9.50: 28%
...
In total my screen was on for about 5 hours according to the battery app but i have my doubts about the reporting. Sygic ( car navigation ) had run for a pure minimum of 30 minutes ( longer because i tested some things at home ), and this usage is not reported at all. And Sygic + GPS are medium/high power drainers.
My 4G/2G + Cell account for 24% of the power usage. Wifi accounts for 4%. My 5 hour screen time supposedly account for 4%...
Its not easy to get a perfect power profile because activities switch, or i forget to turn off the Wifi at work ( so its constantly wasting energy looking for a connection ), with then 4G/2G also active. Or forgetting to turn of the GPS after using the navigation.
In comparrison, my 2 year old Sony Z Ultra, this same type of activity ( minus any GPS usage because i tried to save the Sony Z Ultra from heavy work to extend its life ), resulted in about 2 days of work, before the battery started hitting close to 30 a 40% mark. At that moment i always charged up because it made me unconfortable.
On new battery, the Sony Z Ultra's life was closer to 2.5 days of activity. What is really not bad for a phone that big. Especially if we compare the battery life of most other smaller smartphone's from that time / era.
But the X2 so far is really trumping it massivly. If this was my ZU, showing 27% ( now ), i will have been like "o god, o god, need to charge it up" because its going to drain ( even doing nothing ). I do not have the same feeling with the X2.
And to be honest, i wasted a bunch of power because of the missing ability to automatically turn Wifi off, when your not near your home Wifi connection. So you end up with Wifi + xG active all the time outside. Love to install Trigger or any of the Xposed modules the moment it becomes available.
My estimate for tonight, when i officially hit day 7 ( 168 hours ), is that the phone will have 20% left. Hell, i can probably do another day and half with that. But i think that 20% is a good charge mark. Lower then that will damage the battery more easily ( if you keep low charging over time ).

That's awesome! I'm the opposite of you. I leave the screen brightness all the way up all day, use an hour or more of Navi, do about an hour of phone calls and Facebook, an hour or Web browsing, a half hour of Teamviewer, a half hour of texting, and maybe sneak in a game of Spades. The battery still lasts almost two days. This is amazing in a phone this size. No other phone I've had went this long on one charge with everything turned up. So far I really love this phone and plan on buying another soon.

I know the feeling. Its one of those devices where you do not feel like your limited to x time on it, before you need to run to the charger.
Yesterday did about 30 min car ( 2 * 15 min ) navi with the car usb charger connected. The battery was at 62% before ( did some charging at work using the pc's usb port ) and it was 71% after i arrived home. The problem i have is, was it connected to the 2Amp port or the 1Amp ( its one of those Chinese dual usb ports mini chargers with no description: "what is what" *lol* ).
So still need to figure out if it was charging up on 1 Amps or 2 Amps ( to give me a idea of the power consumption while navigating ). The fact that it charged up while navigating is always a plus.
My old HTC HD2 had the habit of slowly draining while driving with the usb charger connected. Do not remember what my ZU did ( did not used it much for nav, mostly because of the limited battery life ).
So, my X2 is going to retire my ZU & HTC HD2 at the same time.

I know the feeling. Its one of those devices where you do not feel like your limited to x time on it, before you need to run to the charger.
Yesterday did about 30 min car ( 2 * 15 min ) navi with the car usb charger connected. The battery was at 62% before ( did some charging at work using the pc's usb port ) and it was 71% after i arrived home.

My X2 retired every phone I had including the Note 4 and Nexus 6. A seller on ebay is selling our Gold 32gb X2 for $409.99. I may pick up another one to have an extra.
