Okay, needless to say, operating systems like iOS and Android are improving plus the new processors heading to dual core. However, battery technology is way behind I think. What improvements are needed in this field to get a smartphone working for a week on one charge (not realistic but ideal)?
Fuel cells?
New alloys?
What would work to help our battery technology which is falling behind?
Battery technology is far behind but it has been for over 100 years. For electric cars Toyota claims to have a new battery with 2-3x the power density of current batteries. Although for general purpose I believe Lithium Phosphate is still the current state of the art technology.
Fuel Cells are neat technology but not yet that practical just like 10year miniature nuclear cells.
The biggest problems in my opinion are
1. phone size (everything is getting so thin or small in general) leaving less room for a battery
2. screen size (huge touchscreen = big power draw), and other things too that impact battery life.
3. things that run in the background keeping the phone cpu in something other than its lowest power state
4. screen brightness. Seems trivial but can make a big difference and I think all phones should have ambient light sensors are change automatically.
5. internet connectivity. It goes along with #3 in that it wakes the cpu, but also the current wireless chipsets don't seem all that energy efficient. Using any connectivity cellular, wifi, or bluetooth really eats the battery. Many report turning off wifi, bluetooth, and using 2g when possible significantly improve battery life.
Personally I have the biggest battery I could get for my phone and my laptop too. My 17" laptop runs 4.5 hrs at lowest brightness and 3 hrs at the brightest setting. Most phones aren't much different.
Sorry long rant...... does that break down your question correctly?

It sure does for me thanks
nova display and amoled plus is good for battery
li-po is more efficient than li-ion
dual core is more efficient about 40% than single core (in ginger bread)
I've seen in the last months a lot of new roms and I can't try each one of them. So someone can help me to decide what is the best rom for battery life at the moment?
Now I've a defy with the stock froyo rom.
Thanks
i would suggest you http://forum.xda-developers.com/showthread.php?t=1285007 or walters msginger.both have good battery life
for performance cm7,miui,cmiui and the list can go
your choice
You will find that the stock froyo will nearly always have the better battery life than custom roms.

wajkIUI is good
well ive been on miui then on wajkiui all have a good battery life with a moderate usage i can go for minimum a day and half
and when not using is it goes on for 3 or 4 days
Best battery in sleep mode
It depends mainly on 2G and 3G network or Automatically.
Only 2G saves lot of battery
Only 3G drains lot of battery
Automatic is in between. But it trys to hook towards 3G before it hooks to 2G.
Hence in any ROM... if you select only 2G, it will save lot of battery.
2G with manual network selection will still have a better battery.
Yeah barebones had the best battery for me but its not been updated for a bit now then Ms2g 2.1 (I personally love it ) but as mentioned above remember to change to 2G when you don't need internet.

I think the most batterylife gain you will get from undervolting for all ROMS. My settings are [email protected], [email protected], [email protected] stable as rock on WajkIUI 2.2.3
CM9 ICS Epsylon latest version.....endless battery
undervolting.... sometimes is a problem... if network signals are low ... the network radios need more battery voltage... if it cannot get more power... the defy hangs and has a FC.
Same with other apps which need a sudden power.
Main drain comes from 3g and constant connection to internet. Loose those two and you get 7 days at least.

cpu undervolt doesnt have anything to do with radios or anything else. It just affects cpu and maybe Bus speed.
The best battery savings come from turning off the radios, 2g only, automatticaly turn of wifi during data off-peak hours (if configured), screen brightness, and finnaly cpu undervolt. A full review of all of this is in my old post with the name "7 days of battery".
1.Reduce display brightness of your screen
Although Samsung Galaxy S come with Super AMOLED which is supposedly to reduce your battery consumption but ironically it is one of the biggest battery life eater of your phone. Try to disable Automatic brightness and set it to the lowest level will improve your battery life a lot.
2. Remove unused widget in the menu
You must always remember that the more widget you have, the more battery life will be consumed up especially those widgets that use data connection and auto sync based on schedule. PS: only keep those widgets that you really need.
3.4. Turn off Bluetooth, GPS when idle
Only turn on Bluetooth and GPS when you need it, otherwise please disable it as it will consume your battery resources. Or please ensure that the charger is hook on your device when you turn on the GPS in the car.
5. Turn off 3G data connection, use Wi-Fi instead
Always gets connected with Wi-Fi when available. 3G data connection consume more battery compare to Wi-Fi connection. Turn off both of them when not needed.
6. Ensure you phone have a good signal as poor signal consume more battery life
When the phone is at the poor receiving end it will tend to use more power than usual to increase its signal strength with the communication tower. So it is always good to make sure that your phone has a good signal reception. You can try to switch to 2G if 3G connection signal in your area is poor.
7. Try to disable / reduce auto-sync whenever possible
All you have learned, data connection does consume lot of your battery life. By disabling the background scheduled auto-sync applications like Facebook, Gmail and Twitter can save your phone lot deal of battery life. If you really have to turn on the auto-sync feature in the phone try to reduce the frequency of auto-sync will also help to improve your phone battery life.
8. Disable new Samsung Apps notification
You can turn off new Samsung Apps notification if you not using it.
The configuration can be access through ~ >Settings >Application > Samsung Apps > Off
9. Turn off motion sensor
Only enable the Samsung Galaxy S Motion features that you using and try to disable those you not using like turn over, tilt, panning and double tap, turn them off as it might save your some battery life.
10. Use solid black static wallpaper and no live wallpaper
Most of the phone including Samsung Galaxy S Super AMOLED will tend to use less power on just solid black wallpaper than a lively solid white color based wallpaper because there will be almost no backlight on the screen. Please do bear in mind that a lovely animation live wallpaper will even cost you more battery life as ~ CPU power = battery life.
11. Fully close application that not use
Samsung Galaxy S is a super multitasking mini computer that come with dual-core processor but running a lot of applications at the background can actually increase your battery usage because they all require your phone CPU processing power. So it is advisable to fully close all the background applications that you not needed.
12. Freeze unused bundle applications
Too many original bundle software running in your Samsung Galaxy S? Freeze them… Titanium Backup Pro provide a way for you to freeze away all the stock application like Social Hub, Email, Maps that are running and utilizing your phone processing power even when you’r not using them. Ps: Your phone need to be rooted before you can use the Titanium Backup Pro.
13. Undervolt and underclock You 800Mhz GHz CPU
Aside from display, Samsung Galaxy S′s powerful CPU is one of the reason why your battery life eat up so fast. You can just underclock and undervolt it with SetCPU if you don’t need that much of processing power. Ps: Your phone need to be rooted before you can use the SetCPU.
14.Download and install JuiceDefender
With an amazingly over 5,000,000 downloads recorded so far in the Android market, JuiceDefender will definately extend your the battery life of your Samsung Galaxy S. JuiceDefender pack with powerful and easy to use power manager app that specifically designed to extend the battery life of your Android device. It can automatically and transparently manages the utilisation of your S battery like when to enable and disable the 3G/4G connectivity and WiFi.
JuiceDefender is available in the Android Market for free and if you would like to have a more powerful (customisable) version you can download the add-on JuiceDefender Ultimate for a small fee of $6.83.
15. Use custom ROM / firmware
Custom ROM / firmware offer a lot of optimization and tweaks to improve the performance of your battery life. You can try it out if you feel that after you have tried out all the tips above and your battery still draining too fast. But please be reminded that flashing a custom ROM / firmware will be voiding the warranty provided by Samsung.
Please let me know if there are other tips and tweaks to improve battery life of Samsung Galaxy S/Cappy that I have missed out.
I think #14 is not necessary if you are running a custom ROM
why wouldnt it be?
I believe number 11 has been proven untrue in the fact that killing tasks that the phone will reopen soon after actually reduces battery life hence the reason task killers are bad. Also the captivate only has a single core processor.
Other than that nice work it should help people out.
If you use a stock ROM with no voodoo color built into the kernel, then use full brightness, I do and I get great battery life, the screen isn't the biggest battery life sucker.... this isn't the greatest battery saving thread from what I can see.

Generally good tips, but definitely a few holes here and there.
For example, GPS doesn't drain when 'on', only when certain apps use it, making it pretty safe to keep toggled on all the time.
You can go further with SetCPU and other similar apps but underclocking during screen off, and I think that's helping me save battery in my personal experience.
Having a black wallpaper is good and all, but I feel that doing that is a bit too far in optimizing battery life. What's the point of having a pretty decent screen when all you do is use a black wallpaper?
Or flash Darky rom 10.2 Extreme Edition.

That is no good, considering the screen should be taking most of the power.
You either arent using your phone or you are crushing batteries in hours.
No I'm using it, Android OS process in ICS includes more than what they do in GB. It last all day (~15 hours with %40 left)
Sent from my SGH-I897 using xda premium
Yeah I have the ICS port, build three, and the battery sucked the first day due to all the downloading and cpu usage, but after that and a full charge and battery diagnostic wipe it was a great life with decent usage on apps and data and messaging with auto brightness
In Point 11, Captivate uses single processor....and killing system apps causes more battery drains....
My limited experience with roms suggests that as roms are works-in-progress their battery life can vary widely. Serenity6.1 has really seemed to be a long life rom.
These steps do make a big difference, also the Beta 2 build for ICS solves a lot of issues that users had with ICS battery life. Honestly if you want even more battery life grab the 3500 mah extended battery off amazon for $10.

Basically dont use your smartphone as a smartphone. Thats what you're saying by turning off all the good features of the phone.
1, 3, 4, 11 are like NO DUH!!!
5. Are you saying use EDGE? It will save some battery, but you have to consider it may take longer to load something, and thus the screen might be on longer, negating savings. Plus, it's a PITA to change back and forth.
6. Other than switching to EDGE, not really in your control.
7. That's stupid. It defeats the whole purpose of having a smartphone.
9. As long as you lock orientation. I doubt it saves much though...
15. YES, that can be HUGE.

I agree. I think a compromise is a better idea. A lot of ROMs have black wallpapers with a small % of extremely brightly colored random or geometric designs, or green android-ish swirls or something that look AMAZING on the AMOLED screen.
Thank you all for your feedback.

thanks, great guide!
Hello,
Since I have not yet had a precise idea about the battery life of this S10E, I would like a comparison between my current smartphone and the S10E.
If for example with my current smartphone (Galaxy S5 Mini, stock rom and battery replaced about 3 years ago) with the use I make I arrive at night when I go to sleep with about 15% of battery, in my case with S10E how much will the battery percentage be compared to the S5 mini?
Thanks a lot in advance for a reply!
I'm assuming the baterry is 2,100 mAh, the s10e has 3,100 a better processor and a better overall OS and UI.. it handles battery drain better afaik.
You should see very good improvements in battery life going with the s10e..

In all honesty, I came from an LG G6 to the S10e (Snapdragon version), and I'm getting better battery life, even though the G6 had a larger 3300 mAh battery. You should almost certainly see a decent improvement coming from an S5.

I hope, because I would like to buy an european S10E with a Exynos CPU. The battery drain problems is related to Exynos models, not to Snapdragon.
I would not compare a low priced/featured SoC (S5 mini) with a highest end Soc (S10e). A more featured SoC will always drain more power, because it has more components that must be powered. Better compare the energy efficiency of the same SoC from different smartphone manufacturers.
As far as I can say yet after a week, the power drain of the S10e is OK. This means: I expect that with more apps the power drain will raise. If the phone lasts for a day, or if i have to power it in the late evening/night, this is OK.
My last daily driver phone was a Xiaomi Note 5 which broke accidently. That thing gave me power for 2-3 day heavy usage. With an Snapdragon 636, an ernergy efficient mid-class SoC with a 4000mAh battery, the experience was superb. But with lack of many phone features like good camera, NFC, ....
Nevertheless I decided to switch to an higher end daily driver because of the features and overall better possibilies the S10e can give me. If the battery will not last for the whole day i will sell it. I also will buy a backup phone like the Xiaomi Note 7 soon for navigation and for traveling.
I am searching for good custom roms for battery life, FloydQ was decenet but weak internet range, black diamond is good but weak sim signal.
any other options?
