Increase Smart Phone Battery Life - General Topics

Hi, firstly I'm sorry my english is a little bad )
Did you even harder to charge your smartphone is based on the first day? Here are tips that you fully based. Get away from the stress of the outside end charging of battery life and increase your phone.
1 - Home Screen Wallpaper and Theme you are using:
If you are using a smart phone with AMOLED screen, predominantly black wallpaper should be preferred. AMOLED technology while light colors such as white because it consume more power. LCD and SLCD screens, such a situation is not in question.
My suggestion is not to use an animated wallpaper for Android users in particular. Animated wallpaper, using the phone's hardware more. This is going to have to consume more power than the components.
Android users should note also displays add to the widgets. Widgets are always synchronized with the running and intense 3D graphics, as well as the equipment used for the data connection şarjınızı effects shot.
2 - Display Lighting:
It is best to leave the automatic setting of this area.
But I do not like to remain on automatic. If you need to talk I'm being honest, I always light at the highest level. Because all the ingredients here, and it will not have to perform the charging period will be longer.
But I do not want to go up to the maximum number of days gidebilecekse say it, my proposal is worthwhile to listen to. Big and wide screens of smartphones, especially in the light of day very well read. Do not force the phone to the light a little bit, then move to a higher level.
But it starts to get dark, shine your light, especially in the evening turn down the screen. Smart phones display lights to a minimum, even offers sufficient light in the evening. This is an effective tactic.
3 - Wireless Connections:
Smart phones are undoubtedly the most power-consuming units, wireless connections. WiFi, Bluetooth, GPS and 3G that are overviewed, 3G and GPS fully charge the enemy.
According to their attempts, with the closure of all wireless connections between all of them to be open to play at least half a day I've noticed.
For example, turn off the GPS. Only helpful both when business is active. Shortcuts available in Android and Symbian Belle. The option to turn on and off in a practical way. We also do not walk Bluetooth is on. It is also charged unnecessarily waste.
A clear grasp of 3G and WiFi when it is, let's not say conect. When connecting to open it. If you say'm going to necessarily turn off syncing on Android.
Sync / Sync, for a certain period of time it şarjınıza negative effect on the data are drawn. When you use the most sense to synchronize.
4 - Your RAM (temporary memory) Operate the program free to leave and at the bottom:
Most are at fault here. If you open up the application on the phone and waiting at the bottom. E, the processor is running at full speed all the time. The conclusion is obvious.
And then they were going at the charge of the phone as well as the complaints are coming slowly. Take a notebook and a lot of that time in the program's run, so let's wait. Let's see what is going to charge?
There are applications for the program terminates, especially Android. But most of these applications 24/7 has an adverse effect charging them for trying.
I would recommend this program to Android users. Download this app. Click on the widget closes all running applications. However, if you open the program by clicking the icon, you can see and what you want Implementations running off. I would recommend this method.
When you close all the system applications to open them again, the power turns off, and then spends the processor. Here you can download the program[/URL]
5 - Efficiently Manage Your Smart Phone Processor:
This section applies to users Root'lu. Root evaded users have this right, they do not die. Linux-based smartphones, especially those driven into exile in the market with a certain processor speed settings.
In general, the phones are set to OnDemand, the processor can adjust the speed according to the amount of use. For example, a 1 GHz processor that the phone does not work all the time at 1 GHz.
Their phone for the sake of example, a 1 GHz - 265 MHz range is running. I changed speeds. If you charge the phone and the maximum to withstand reduced from 500 to 128 can do. But later in your job will be completed on the processor to use 100% of himself. This will mean that the screen backlight to stay on and wait for you. I mean, at least let it charge the struggle, suffering Pull spend more charge.
I phone 1190 - 450 range using the. I can do my work as well as installing and getting faster. Charging time is important, 1190 - 128 range I choose.
Forget! Reduce the processor speed on the phone, when trading amplify şarjınızı. Because it is trying to slow the processor 100% to use and work will be completed on your screen light will stay open late.
6 - When charging the phone's battery Full Fill:
Do not say we already have would remove 100% charge to fill it. Phone software does not fully charge the battery. Leaves a certain margin of tolerance. Here we also benefit by it. In particular I saw that HTC Desire'da tried and successful. Each company's share of each model, it will not stop. But you can be on your left. Does not hurt to try.
Explaining the steps for:
-Phone up to 100% of full charge.
-Turn off the phone, remove and charge the phone.
-Install and charge the phone again, wait until bekleyebildiğiniz. (1-3 hours)
-Turn your phone into the phone, and remove the charge.
-Wait for your phone to do nothing between 2-5 minutes after opening. (Not attached to Sharjah)
-Turn off your phone again and again for at least half an hour into charging.
Remove and use the phone in the normal-charging. The procedure is finished.
This method has been calibrated with the battery is charging and fully. Enough to do this once. And then he goes to full charge.
7 - Special Edition Operating Systems Aim for:
Android users who root for in this Article. Made by the manufacturers of Android devices, phone skins, chargers doing negative effect on life.
TouchWiz, Sense interfaces, such as, the system is more tiring, as they lower the charge time. So we have the benefit of using a pure version of Android.
With pure Android versions like CyanogenMod custom Android versions sure to use similar interfaces. The term of charge with a very stretched. Will be surprised.
Of course, I do not recommend this method to anyone. Aware of the change and the risk of all the phone's Android software will recommend it to our readers.
Suggestions useful to you?

Thanks!!! i will follow these tips :good:

Monitoring battery life vs usage

On a Diamond I was using battery log to see the effect of various things, data use, push email, tf3d, screen brightness etc.
I was expecting to get best results from following the usual guidance of turn off whatever isn't being used, close programs, dim the lights and such.
I found that some programs do indeed use more memory and cause a bigger drain but many do not. Neither did a gprs connection when left connected.
However, i noticed spikes in battery when opening and closing programs, and disconnecting the data connection. Therefore from this it would seem that I am better off leaving programs open rather than re-opening them many times, and also leaving data connected.
Does anyone have any thoughts on this? This is assuming that abttery log is accurate, I don't want to slam it and say its rubbish, i don't believe it is. I am not sure HOW accurate it is though.
On a side note, people are advised that charging from teh mains is better for the battery. It is certainly quicker but i always thought that trickle charging batteries got them more fully charged (eventaully). Is that based on ni-cad rather than li-ion?
I haven't found either of these topics covered exactly as above so I hope this is not a repost.
I've done a lot of battery logging myself. There isn't really a correlation between memory usage and current flow, like most people think. Having repllog.exe idling in the background doesn't do anything to the battery, in my experience. I don't have data (and only get EDGE), so I can't comment on gprs and the like. Turning the screen off makes a huge difference in consumption. The one weird thing I notice on my fuze is that the current tends to cycle between a low state and a high state with the screen on; it doesn't do it with the screen off. So, if I'm listening to Core player with the screen on (just a random level), the device may alternate between 150 and 240 mA. With the screen off, it will hold steady at 90 mA. This is without any other apps running and with the phone off. Even with nothing running besides background processes and the screen set at 1, the current will fluctuate between 65 mA and 140 or so mA. It's mostly at the lower current, but the higher current consumes a lot of juice.
Long story short, if you're on a plane and are listening to tunes, turn the screen off. Or, if you're running your gps and are hiking or something and are keeping a gps log, again, turn the screen off. You can save a lot of battery that way.
Oh, yeah, I forgot to mention that for a while I tested out no2chem's clock control to see if it saved battery or not (this gets to the accuracy question). I would lower the clock speed on my fuze, and then start logging and compare the current draw under a similar situation at the normal 528 MHz clock speed. I never saw a difference in current draw, although the device would clearly slow down (sometimes too much to be useable). I'm not sure if tBattery was really accurate under those circumstances. It's possible that the lower clock rate messed up the log measurements by a proportional amount, but I just don't know.
I assumed that two-level jumping was because I was constantly opening and closing stuff to measure the effect, and there was a delay in battlog showing this.
I thought it could also be something to do with the radio, but you found it only happens with the screen on. Delayed reaction to the backlight dimming?

how to compare a power consumption of your devices

So, for a long time reading the forum and asking a question along the way, why I have so quickly battery discharging on my phone, I came across an interesting thought: "and from what I actually compare?. someone wrote about 5% per night, someone love to confess on the tab "Journal of the battery and it shows that he is the difference between" running "and"phone on "0.5%. but what is a night (for me it's 8 hours for someone 5). which network who have (GSM or 3G)? Also, we are constantly being developed and modified ROMs and kernels, which also constantly featured the words "lowered energy consumption."
And how do you actually compared the energy consumption of the old firmware to new. usually it sounds like "on the old firmware, I charge the phone every day, and now I charge every 2 days." but we don’t know details of how actively you used options of your phone on the old version, and how use now "(for me, For example the first 3 weeks after buying the phone had lived only one days, but now 2-3 days. but not because the new firmware, but because I'm tired of constantly digging through the phone settings and install the different soft, thus discharging it).
So, our challenge is to develop an algorithm (and in the future opportunities programs), as can be correctly and objectively compare the power consumption of our devices. That at least from the transition to the firmware to the firmware, from one kernels to another to be sure that the phone will not live less than before. Search for programs of this kind I have not been successful, can someone tell me if he knows?
actually look to you for ideas, how best to develop an algorithm testing the phone, and simultaneously bring your own.
then everything will be set out with respect to the software part, because hardware is not subject to us
1. So, first of all we need to start with any initial data. Having read all the threads about power consumption, I have come to the conclusion that the original data should include the following:
- Do wipe battery stat. We fully discharge the phone till shutdown and charge it in off state. after the device is fully charged, unplug it from the charging device and do wipe batter stat from the recovery menu
- To make the calibration of the battery you need to discharge and completely charge in turned off state the device at least 3 times
Here is one of the toughest parts, considering the long battery charging our phones. charging off-state means 4 hours of losing connection. and we need to do it 4 times. One discharge-charge cycle for a complete calibration system, as I understood , is not enough.
all the widgets and programs that can perform any action to in background must be disabled.
well, and then discharges our apparatus up to 95% in quiet mode, to give the battery a little bit cool, and eliminate trouble with 99-98-97% and you can begin testing.
2. Measurement tool. I would have chosen for this purpose, program or Battery Monitor Widget (she effects on discharging battery, but it writes logs, which can be tracked over time the battery status in percentage and millivolts) or JuicePlotter (don’t have logs. We have to extract data from the graphs that it constructs). JuicePlotter showed the best result in power consumption while the CPU time drain more than BatteryMonitorWidget - here's the first interesting fact. Now I’m testing these programs repeatedly to confirm this effect
3. In order to reduce measurement error the device must be discharged at least 20% of one test. or better at 30%. then + / -1% in the testing will not be particularly significant. That why testing process will be long and tedious.
4. In order to understand the power consumption of device in general, you should at least try to understand and share the power consumption of its individual components:
5. power consumption of the screen. For this purpose you can use the widget to extend controls, where you can turn the screen on constantly. And choose any standard wallpaper with middle brightness. we need to measure how much battery discharging for 3 hours the screen on. for small, medium and very high brightness, respectively. you can check consumption on the automatic brightness too. is believed that the turning on an automatic brightness strongly discharge the device..
6. power consumption of the file system. In the good we ought to write a program that creates a file in a loop on the internal flash drive, and anything he writes and deletes the file. Repeat the loop few thousand times to the total time was about 2-3 hours. but until there is no such a program, you can simply copy the file size of 2-3 gigabytes of internal memory with a program such as ES Explorer. In this case, the screen must be enabled to minimum brightness (since we already know how much the phone is discharged from simply turn on the screen) to control the copy process and accordingly the percentage of discharge.
7. Estimation of consumption of the processor. To do this, too, we can write a program that would do any arithmetic operations within an hour of time. But here we get the maximum load, therefore the maximum power of the processor. and it is unlikely it will be different from the firmware to the firmware . But our processor is also able to reduce the frequency and consequently reduce power consumption. And here I think there is much to improve the software. Therefore, must be differences from firmware to firmware. And the best test for this, I think, show any video on device, it loads processor to 30% on average (better view a videoconcert, so there isn’t quite boring) for one hour and thus measure how much discharge our batteries from this view .
8. Estimation of Wi-fi. Then the test can serve up any file copy from PC (connected through wires to an access point, so this segment was not the brakes) to our unit. Since the maximum speed that I managed to squeeze out of the standard N on my Captivate is 0,8 MB / sec I think copying the file size of 2GB will be enough to discharge our device is not less than 20% battery. copy can be perform using the same ES Explorer
9. Rated power consumption in standby mode. here it must enable the network only GSM. turn off the wi-fi and bluetooth. the screen went off and did not touch the machine for 8 hours. Better course would be 24 hours, but I think hardly anyone will be able to perform such a test
Actually look to you for your suggestions and additions, as can be realized by comparing energy consumption of our devices.
from the general collective thoughts we can open thread with algorithm, where you can write your test results according to the algorithm ... and make any conclusions.

10 Tips To Conserve Your Smartphone Battery
By Michael Poh. Filed in How-To Guides
New: Top 5 Tools of DevOps. Get the Free eBook Now!
Apple, BlackBerry, Samsung and other global brands have come up with smartphones equipped with powerful mobile operating systems such as Google’s Android, Nokia’s Symbian, Apple’s iOS, etc, that allows users to play games, listen to mp3s, snap pictures, have access to the Net and even stream videos.
Given their diverse range of capabilities and multi-functionality running on a mobile (as in on-the-go) platform, it’s no wonder that battery life has always been a concern for developers, manufacturers and the users themselves. On average, most smartphone batteries last between one and two days before being completely depleted, and in need of a recharge.
Increase Battery Life

While we wait for the hardware development to catch up, the alternative will be to conserve battery life. As it is with our energy levels, battery life can be effectively utilized and managed, leaving nothing to go to waste. Without a battery charger or a spare battery with you everywhere you go, you’ll have to make due with minimizing the consumption of battery juice.
Here are 10 essential tips how you can conserve your smartphone’s battery.
Read Also: Top 10 Security Tools For Your Smartphone
1. Turn Off Vibrations
Vibrations are great for notifying you about incoming calls or messages when you’re in the theatre, meetings or other places where it’s necessary to keep the phone silent. In places where it doesn’t matter, it will be better for you to use your ringtone as notification if you want to keep your smartphones on longer.
Vibrations actually use up more power than ringtones. The sounds produced by ringtones are just very tiny vibrations in your smartphone’s speaker. Compare that to the shaking of the entire phone via vibrating a smart weight, playing a ringtone definitely zaps less of your battery. The same applies for using vibration for tactile feedback. If you don’t think it’s necessary, then disable vibrations or at the very least, lessen the magnitude of the vibrations.
2. Dim Your Screen
This one tip affects battery life drastically. It’s obvious that dimming your screen will reduce your smartphone’s power consumption since we all have to activate the screen whenever we use our phones. If our screen is brightly lit up every couple of minutes when we check our emails and such, it eventually will zap battery juice. Auto-brightness setting enable the smartphone to adjust the brightness to its optimal level for reading while conserving battery life.
On the other hand though, you may consider tuning the level permanently to the dimmest level that you can still read under without straining your eyes. Doing so may do wonders to your battery life in the long run.
3. Shorten Screen Timeout
In the same manner, if you wish to minimize the power consumption of your smartphone of the screen display, you ought to consider shortening the screen timeout. This decides how long the screen will remain lit after you finish interacting with it.
Some of us do not have the habit of ‘locking’ the phone after we we are done with it; we just let it go lights out by itself. Keeping the timeout duration short will ensure that the phone doesn’t waste power when you’re not using it.
4. Switching Off When Inactive
Although it is true that turning on your phone consumes more power than unlocking your phone, switching it off for a couple of hours can save more battery than leaving it on sleep or inactive mode. If you know you’re not going to touch your phone for an extended period of time, such as when you’re attending a meeting or sleeping, you can actually cut down a significant amount of energy consumption if you simply switch it off.
You might be wondering why you should even bother about battery level when you’ve a charger with you at home while you sleep. Well, the thing is that repeated charging for certain kind of batteries eats up the battery volume. For such batteries, the best way is to conserve as much as you can so that your battery retains its original capacity as much as possible.
5. Charge Your Battery Correctly
Speaking of phone charging, there are generally two kinds of rechargeable batteries commonly used for smartphones: Lithium-ion (Li-Ion), and Nickel-based batteries: namely Nickel-Metal Hydride (NiMH) and Nickel-Cadmium (NiCd).
The battery capacity in NiCd batteries are reduced every time you recharge them. Nonetheless, NiCd batteries have longer life cycles i.e. they can be recharged more often than NiMH batteries before stop working. Nickel-based batteries should be charged (to the full amount) when they’re more or less out of power, and not when there’s still a good amount of energy left.
(Image Source: Slairea)
Li-Ion batteries have the longest life cycle among the three types of batteries but they also need to be charged more frequently (even when the battery is not fully used up) to maintain its original capacity. To keep your battery lasting longer, find out more about the type of battery that your smartphone uses and maintain the appropriate charging strategy for optimum usage.
6. Close Unnecessary Apps
Some of us open app after app and don’t bother to close them even after we no longer need to use them. This multi-tasking capability is a common feature of smartphones, but it is also a main reason why battery life gets drained away easily. The worst thing is that you’re losing battery juice when you are not even using them. Leaving them open will leave your battery at half-bar in no time.
As often as possible, kill your apps if you are not using them. There are some valuable apps out there that manage the multitasking ability of your smartphone to ensure it performs at its best to conserve battery life without jeopardizing usage. One such Android app is the Advanced Task Killer.
7. Disable GPS
Certain apps eat up more battery juice than others, particularly apps which utilize the GPS system to track your location. Your smartphone has a GPS unit that allows the sending and receiving of signals to and from satellites to determine your exact location, which is integral for some apps to work, for example, map-based apps like Google Maps or to check-in on Facebook.
(Image Source: Fotolia)
When left running in the background, some of these apps may continue to send and receive signals. It takes a lot out of your battery to continuously do that, even if you aren’t aware of it. Hence, you should ensure that those particular apps are closed when you really don’t need them. A more extreme way is to disable location services when prompted by these apps. It may slow down the efficiency of these apps but you won’t be tracked on your location and some users deliberately do that for privacy reasons.
8. No Bluetooth, Wi-Fi, 3G/4G When Not In Use
Energy is consumed whenever your smartphone searches for signals, Wi-Fi, 3G or Bluetooth etc. When the reception is poor, the phone will continue scanning to attain a good connection. Repeated searches for these signals can easily make your battery level drop a notch.
What I’m saying is that you should turn off your Wi-Fi or Bluetooth when you don’t need to be connected. One convenient way to do it is to switch to ‘Airplane Mode’ or just switch your phone off when you know you can’t get any signal.
On the other hand, when you need good reception for your smartphone, place or position your phone in high connectivity zones. This will prevent your smartphones from constantly seeking for a connection and wasting your precious battery power switching from one signal to the other.
9. Minimize Notifications
With constant connectivity to the Internet, we tend to get notifications on our smartphones all the time, be it updates on the latest news, emails, high scores from games, add-ons for apps etc. But I’m sure that you would only want to be notified on the more essential stuffs like new text messages, or messages from Whatsapp.
(Image Source: Taakoses)
Not only is it annoying to constantly receive irrelevant notifications that can actually wait, it is also a powersucker for each of these notifications. Every incoming notification will light up your screen, make a sound alert or vibrate.
Manage your settings well and disable unnecessary notifications to save a little battery power (and avoid being frustrated with these constant notifications).
10. Maintain Cool Temperature
Some of us might have observed that our battery runs out faster when our smartphones are warm. Put simply, don’t leave your smartphones under direct sunlight or in any place that is hot.
One of the more common occurrences would be leaving the smartphone in a car parked under the sun. The battery will function optimally in cooler environments, so do look out for, and try to avoid, scenarios where your phone is exposed to unnecessary and excessive heat.

[How –To ] AMOLED SCREENS: Evidence of battery savings using black ,bright wall paper

EDIT: Please jump to post 4 for updated test results . Come back to this post for why this thread
There are umpteen threads on battery saving tips / methods and a few on AMOLED screens and battery savings. So why a new thread, could be the Question
Because
1.Battery saving means are meaningful if backed by numbers, else it’s subjective
2.Tests below were done on N7100, but given the popularity of AMOLED (two dozen and counting per Wikipedia), across cell phones and tabs, this may be interest to battery freaks and hence posting in general section rather than N7100 threads
3.Provide a replicable methodology of testing on your AMOLED device (rooted) both manually and automated. There are threads on XDA as well that suggest testing methodology but have not come up with easy testing methods and automating it unless I missed
I am NOT a qualified guy to understand the technical details of testing screen power nor of the methods/ apps used. There is enough material on the net to show how complex it is and savings using using dark screens vary from 18 to 41 %. IMHO, the jury is out and appears to be taking a long break
All I have done is put together various pieces to show a way of testing it and come up with results that are indicative and demonstrate trend lines.
Also the apps chosen for testing is not be misconstrued as canvassing for them.
There may be better ways of doing this test using other apps or better testing ways, which you are welcome to share here.
Test Device Configuration
GT-N7100 (t03g), ROM- Deep Impact (Morph variant) (Kitkat) by @Sammy_052
Kernel Agni- 3.0.101-India-v4.4.2-OC-INTL-STOCK_HYBRID-KitKat
Apps Used for testing
3C Tool Box Pro: Has a nice feature showing screen consumption in mAh (though on devices like mine which don’t have a current sensor, it is derived from battery drain percentage). Plus, it has the advantage of modules that can be accessed and test automated. Immense thanks to @3c , developer, who helped a ton
Darker : Screen Filter that was thoughtfully provided in the ROM. Free version allows darkening up to 50% as used for test
Stay Alive : To keep the screen alive for two hours (being the test duration), since the maximum screen time out is limited to 10 minutes in KitKat. 3C Toolbox offers a way of choosing apps , which keep screen on, as long as apps are kept in foreground. For some reason, this did not work with Nova Launcher as chosen app, hence the need for a different app. There are many free apps on Play Store with similar functionality and may be used after testing that they do not impact 3C
MacroDroid : To automate the test process. This is by @UndeadCretin and is a great tool to automate without a steep learning curve. The aim of click starting the test and getting results in mail box has been achieved (barring manual intervention in the first minute of starting the test) . The macro used for this is posted on the app thread. This macro can be easily tweaked and battery bugs can have a field day trying things like Live wall paper, under volting/over volting and altering CPU / GPU frequencies to see impact on power
Broad test Methodology (details later in thread)
Screen power usage was tested in 3 cases. Cell was kept in airplane mode to get cleaner results (optional) and Stay Alive used to keep the screen on for two hours ( targeting to get a drop of 10% battery level) for each test.
Case 1: Bright wall paper
Case 2: Bright wall paper with screen filter
Case 3: Solid black wall paper
Results of Testing ( files attached )
Case 1: Bright wall paper: Screen consumption is 195 mAh
Case 2: Bright wall paper with screen filter: Screen consumption is 189 mAh
Case 3: Solid black wall paper: Screen consumption is 172 mAh
Conclusions
1. Using a solid black wall paper as compared to bright wall paper shows 11 % savings.
2.Using a screen filter on bright wall paper shows very little savings 3% . Was surprised at this result and repeated the test and the results were practically same. This disputes the accepted belief that screen filters save power but is savings as low as this?
Internet reports savings from 18% to 40% by using black screen as compared to 11 % above, am guessing are due to a bunch of reasons, like testing methods, screen size, age of device, device to device variations, ROM, kernel settings, GPU/CPU voltage and frequency to name a few at device level .At next level, is the apps used, usage pattern of phone, algorithms used for dimming the phone and many more.
Testing as above is not real life. To carry out real life testing, ideally one would need to replicate activites for a fixed duration like calling, texting, browsing, watching stored video, on line music / video. I have not come across any app or way of doing this and would be happy to give it a shot, if someone can suggest a simple way
Detailed Test Instructions - To provide consistent testing environment and get clean results
1.Disable scheduled running of apps during the test and Greenify
2.Set the wall paper which you want to test and ensure sufficient battery
3.Run Stay Alive and use the second icon (red one) in the notification bar
4.Run Darker at your preferred settings for tests with screen filter
5.3C settings ( Thanks to @3c )
a)Settings>Recorder>Continuous recording enabled
b)Settings>Recorder>Time frame and Rate- depending on how long (maximum) you want to test and how frequently you want data to be updated, choose appropriate option . I used 12 hours, 10 minutes
c)Settings>Battery>Monitoring> mA retrieval method (if your device is listed choose, For Samsung devices, on enhanced estimated or estimated on the other side is pretty stable and the same for all devices, but often slower to update.
d)Settings>Battery>Monitoring>Estimate, use estimates drain, or if your device has a current sensor and reliably works choose use current sensor
6.Create shortcuts on home screen for battery statistics module of 3C using 3C widget
7.Start the test and go to markers tab and set the marker. You can create markers from the action bar or from history tab long pressing a record. Markers shows average consumption, be it mA or %/h (tap the value to switch). Min/max shows the range for the % or mV. Remember to show full history (not just % changes) by long-pressing the options and tapping “full history”.
8.Time the test and take screen shot of markers results
9.Repeat test for different cases
Looking forward to your views
Nice
Wow, this is a totally put together review. AmoLED screens save a lot of power on black, unlike LCD backed by light from LED where the entire screen needs to be on at all times when the screen is displaying anything. LED screens do not have a back light to support them in producing light. The individual pixels themselves produce the light. Hence if part of the screen is black, it means that, that part of the screen is off.
I had thought this through when making the rom in the first place and hence was the need in keeping all the elements either complete black or white. But samsung as a company decided to go away from this beautifying and practical aspect and the later phones have begun shipping with rather different set of colors.

Click to expand...
Click to collapse
Thanks for your view. It is fitting that you as ROM developer, included this aspect in your ROM and that is what triggered me thinking.
The test above is representative of a small portion of SOT, maybe around 10%. Real life usage is what needs to be measured and am searching for an app that can run fair amount of real life use cases. Only Antutu does something similar but requires user intervention to run. Ideal is auto play so that it can be automated through MacroDroid. Your thoughts around this are welcome
Sent from my GT-N7100 using XDA Free mobile app
Updated test results
So, i was stuck for long to do real life testing and it is done now !!!
A few major changes from the previous set up
1. ROM changed to wesam.othman v8 by @wesamothman
2. Better Battery Statistics (BBS) used in place of 3C Tool Box mainly because of ease of setting up and being more popular, eliminating process described in OP. But IMO, 3C Tool Box is far more versatile and powerful in studying battery usage
3. Most importantly, discovered Battery HD app (free) by Small Tech (https://play.google.com/store/apps/details?id=ch.smalltech.battery.free&hl=en). Very hand app and well designed. This app has on line calibration features using wifi browsing, streamning music and video. I wanted to extract these modules and incorporate in the macrodroid macro (part aim of this test is automation as mentioned in OP). Requested the developers and amazingly, they jumped in to help and created separate links for each of these modules so that i could call them in the macro to execute without any manual intervention. Extremely thankful to Santiago and Vadim of the team who made it possible :good:. Without their help, automation of this test could not have been possible. Thanks again !!!
Coming to the test , real life usage to the extent possible has been simulated except for gaming, calling , texts and social media apps. Test consits of 30 minutes of browsing, 15 minutes each of streaming music and video. Screen was kept on during the test duration and darker (screen filter) when used was set to 50%. Pics attached
Results
Case 1: Bright wall paper- Batterydrain was 10 %
Case 2: Bright wall paper with screen filter - Batterydrain was 9%
Case 3: Solid black wall paper - Batterydrain was 8%
So, this may be interpreted as- if you get 5 hours SOT for instance using a bright wall paper , you would have drained 50% of battery. But with using a screen filter on the bright wall paper, after 5 hours you would have used only 45% and the extra 5 % (over usage not using screen filter) would give you additonal 30 minutes of SOT !!!
And if you were using a solid balck wall paper instead, that would have given you an additional hour , making it 6 hours of SOT !!! ( Of course, this is assuming same usage and linear battery drain)
So, it is your choice, you can test it yourself
Happy battery life...cheers

This Is How You Can Boost Your Phone’s Battery Life!!

A smartphone is a necessity in today’s world.
​Doesn’t the battery life of today’s smartphones bother you? I’m sure it does.
What could be a possible solution to prevent the loss of battery?
From the times of Nokia’s 2100s when a single charge would last days to contemporary times where an expensive handset won’t stay charged for even one full day, smartphone batteries have in fact seen a downward trend in their graphs of performance.
What You Should (and Shouldn’t) Do to Extend Your Phone’s Battery Life
We do understand with smartphones, the consumption of power has only increased way too much. A solution like increasing the milliamperes of a battery is a like running away from a feasible solution. Until we find a solution to either replace the milliamperes of a battery, let us cover some ways in which we can help our battery last longer than usual. In this article we elucidate you about ways that are a sure to help you save those milliamperes for the last mile of that game or that important call you wish, you could have done.
What Drains the battery?
To cure a disease, it is important to figure out the pathogens before going for the resolution. Likewise when it comes to smartphones, we need to figure out the the exact cause behind heavy drainage of our battery. Turns out a mobile’s internet connection and your screen are the biggest battery drainer. A lot of activities require the screen to remain active ; things like playing a game or watching a movie. It is something we can’t avoid obviously or what’s the point of making a portable device
What sucks the battery
When we watch a video or play a graphics intensive game, a lot of things are happening in the background. Like when you fire a video or play a game, every sense organ of that device is in action, the speaker, the screen, the processor and even the internet connection. With time, games are getting even more intense which is further an issue for smartphones.
Another issue can also be the over usage of GPS or navigation. A navigation requires you to turn the location services ON and when that happens few things drain the battery very quickly. First and foremost, your screen will alway be ON. Also when you go by the navigation, the app forces the GPS circuitry to refresh the app more than the normal rate. There is also heavy involvement of wifi or cellular data which is where a fair amount of battery drainage happens. So the next time you are making use of GPS, do make sure that your device is connected to a power source so that there is no sudden drop in the battery of your device.
Easy Solutions
A smartphone is a necessity in today’s world and battery is an integral part of it. However as a user, you can always make sure of a few things which can help your battery last longer. All the suggestions made below require very little technical knowledge.
1. Use the screen less—or at least turn brightness down
Use the screen less—or at least turn brightness down
If we could draw a graph using the things that consume the maximum battery then your phone’s screen would top the bars. Today there are tons of things that consume battery.
A random video on facebook or normal browsing even for a small time can affect your battery.Apps like snapchat and even games like Pokemon Go drain tons of battery juice due to continuous usage of screen and the heavy reliability on the GPS.
A good way is to try and limit your usage of screen intensive tasks.
Another recommendation is to reduce down the time that takes your phone to lock off automatically. It might seem unimportant, but in the long run, you will realize the impact it has on your battery. Almost every smartphone has this feature where you can alter the lock time time to a few minutes or even seconds.
In android phones,
Click on “settings”,
Head towards “General settings”, click on auto lock which shall show the different timings that you can set.
Select the least time that you can set.
If you own an iOS device then go to settings and click on display and fix the sleep button. A wise way is to manually click the lock button the moment you’re done with your wok.
There is another tweak that one can do where you can necessarily set the brightness of your phone to auto. There are many who set the brightness of their phone’s screen to a limit that they are most comfortable with. Since you won’t always be under the same lighting conditions the whole day, it is highly recommended that you enable the auto brightness ON. It will set the light automatically and also help you save battery in the long run.
2. Use an ad blocker
When we talk about ads that appear in your browser. They are usually sources that are mediums of earning for people who have it on their sites. The problems arise when you browse such sites ; the ads pushes your browser to use a little too much battery. You might have been bombarded by flashy ads with gifs and videos while browsing the net. It is those ads that drain a lot of your battery juice.
A proper solution to this problem can be to use a browser such that it will block all the ads that pop-up. You can even install an ad blocker.
3. Switch from push to fetch Email if you have many accounts or get lots of Email
Switch from push to fetch Email if you have many accounts or get lots of Email
Push notification is a popular option in today’s smartphones where the user is notified of any incoming email. The user will be notified as soon as there is a message that hits from the central server. Push notification is a wonderful thing that helps you stay connected but for that it has to be always connected to the central server and so the internet. Net is always required for syncs and message delivery which drains energy.
4. Store music locally
With times, everything is being stored in cloud More and more people usually love to carry things that they can easily sync with their other devices.
There are many music streaming services such as Pandora, Apple music, Google play music and Spotify. Whenever you use a service that requires you to be always connected with the internet then it is sure to eat away your battery.
Any service where wifi or cellular data is mandatory will require you to be connected to the internet always.
But there are ways in which you can tweak them. You can opt for offline downloading so that whenever you wish to enjoy music, you can simply tap once and play your songs after having saved them over WiFi or by using your internet pack for a short time. It will free the phone from needing to always be connected to the internet. Also storage has become extremely accessible these days so you can easily download a and carry all your music with you. It will not require any internet and more importantly no more battery drains.
5. Avoid extreme temperatures
A smartphone battery is like an engine that produces heat with continuous usage but if the outside temperature is not suitable then it can have some impact on the overall quality of your battery. Even Apple once stated that the device battery shall last longer if the temperature outside lies in between 62 degrees to 72 degrees. Even when the conditions outside are very cold, battery life is shortened. The exact same happens when the phone gets heated up because of outside condition. These two conditions are sure to shorten your battery life so it is always recommended to keep your phone in optimum conditions.
6. Use airplane mode or low-power mode (if you must)
In both the platforms whether it is iOS or an android phone, there is an option called airplane mode. It was made so that when you travel on board a plane, your mobile network should not interfere with the communications happening inside the airplane. There are many good things that happen as part of initializing airplane mode.
One you end up saving a good amount of your battery life. In fact, you should enable the airplane mode at any place where you will be having poor range since there is no point in letting the phone use all of its power in finding range for a network. Your phone works even harder when it knows it isn’t getting the required range to gather any network for basic communications. When you use a phone in airplane mode, the battery drainage is very less.
There is also a feature that we have recently started to see in the latest android version Android oreo in which you can enable your phone to low power mode where in the phone automatically shuts down the tasks that are always sucking the battery out of your phone.
It is also often called as battery saver mode. In both the phones, you get the option where the phone automatically enters airplane mode once it knows that the battery has drained below a certain level. In such a case, the phone shuts applications and services which run in the background that are generally running when your phone has a healthy battery.
