I read about this let's hope it's something viable/affordable to be included in our phones. I use my phone a lot and have many email accounts I usually get about 15 hours when at work however on weekends I get a day or two of use so this could really be useful

I agree. Also, I'd love to charge my phone in 30 seconds. It's a different approach to solving the battery-life problems.
If you can't make a battery that lasts longer, make charging faster.

One of the best tecnological improvements since camera...

That makes so much sense, I whole heartily agree

About time battery tech evolved in 1 way or another.

That's a website full of very classy people...

The energy density given is not bad for a supercapacitor, but the ballpark figure 'comparable to normal batteries is only 10% of chemical batteries.
So... your phone may recharge in 20 seconds, but only run for an hour or two.
Still it is great progress. Imagine a normal battery for the long runs, and this quick charge capacitor for a fast recharge in between.

REALLY bad battery life, is this normal?

Heya,
I've used my One for a few hours now, I'd say moderately heavy use (checked facebook/twitter, downloaded some apps, watched a few youtube video's, played Dungeon Hunter 4 for 30 minutes or so, checked flipboard).
I'm amazed by the poor battery life, especially since all the reviews were so positive. Will it get better? Could I have a faulty battery? This is nowhere near the 14 hours people have been talking about...

you can't tell yet. @Zepid, look for better battery stats xda edition and install it and post the screenshot for kernel and partial wakelocks, other and process.
It's hard to really tell with the default battery monitor, try BetterBatteryStats or GSAM from a full charge and go from there.
Also turn Power Saver on. It limits the CPU to 1.1GHz, and won't even affect gaming performance, or anything else for the matter except benchmarks. Click on the Power Saver option to customize what gets turned on/off.
You should check out the thread that talks about battery saving tips. It helps a lot and make sure you install a custom Rom such as trickdroid.
It's very battery efficient.

Don't forget that if you install a custom ROM, you'll need to root your One. That also means loosing your warranty

DH4 is a beast on battery in my experience. It is hard to play that game and not burn a ton of battery.
Anyway, when I don't play DH4 I still get 5 hours screen time. That's without power saver, auto sync disabled, and Lux adjusting screen brightness. I'm sure if I used power saver I'd get much longer.
Seriously, give it a couple of days!

I have found my battery improved after about a week of having my phone.
Graphic intense games like Dungeon Hunter 4 EATS the battery.
Thanks guys, the Power saving feature definately seems to help, and it's not slowing down the phone at all. I'll give it some time and see if the battery life improves.

You should allow more time, at least 2 or 3 updates, to iron out the biggest bugs. All manufacturers need that time, apple en Samsung too.

Nexus 5 Battery Results

Post your screenshots with a description of the test you used. ​
I'm doing a low to medium usage test with Bluetooth, Location Access on High accuracy, WIFI, HSPA,Auto Brightness and google now. From 100% down to 0%. Then doing a Full charge time with phone turned on.
Will be posting screenshots via dropbox below with a few hours in between.
Battery usage screenshots. https://www.dropbox.com/sc/zwr2s240knxqove/_FZDWDZWmT
4hr 6mins screenshots of time on. https://www.dropbox.com/sc/zzvlu7oplnax7qf/IeDdDl9Nb_
8hr in with screen on time. https://www.dropbox.com/sc/ww0uwt5fo8tbuk9/mw_LPAcrB3
19hr screenshot with 7.5hr overnight standbyhttps://www.dropbox.com/sc/t64536q9a0l0axd/RWJ6_Oq4gJ
In addition I've used a2dp audio stream for an hour or so. I'll do a full screenshot of all the on times later.
Still very low usage scenario. Battery looking good. @22hrs 40% with updated screenshots above.
Final Result only took me to 15% with 1 Day 16 Hours. Screen on time 3hr 16mins. Needed a full battery for the day and couldn't risk it but atleast it's a general ballpark. https://www.dropbox.com/sc/oaj33ji9kssx5rt/BFiLIz-Jef
40 Hours is still pretty good for light usage. During a busy working day i would be happy with 9 hours max usage.

It looks ok with almost 2h of BT streaming calls + 2h of music. Other results in thread seem more "realistic" (if you don't use BT). Let's wait for more feedback. If it could make 4-4.30h screen on for me, that means with custom kernel and UC it could easily hit 5h or more. *thinking out loud*

Here's my reply from the previous thread...
Well you say it's disappointing but I disagree;
If you look at the screenshots you will see how much battery has been taken by the voice calls compared to screen on time;
30% of the total battery use was from the 3hr47m for screen on time but...
A whopping 26% for only 1hr28m of voice call time! If we use that ratio and just double it (assuming all network strength was the same) you'd likely lose 52% of your battery in just under 3 hours...(this is just an estimation based on my results btw).
I honestly don't understand the hard-on people get for screen on time when voice calls seem to drain the battery much much harder... doesn't anyone use their device as a phone anymore?
Also if you take into consideration how bad my signal was the battery life I had today was all the more impressive.
A Random Afterthought:
IF that 26% that were used on Voice calls were used for screen on time...although realistically it'd probably be something like 17-20% with the rest on random android processes and processor usage; the screen on time could easily be above 5 hours possibly pushing 6 with bad signal and no wifi O_O...
Well nexus 4 with Trinity kernel gets 6-7 hours so with nexus 5 I expect around 8 hours on a custom kernel and stock should get around 5 hours which is pretty darn good.

shr33kant,
The battery performance results you have are perfectly acceptable for a typical phone user that uses the phone for calls, web surfing, google services, movies etc. I only get 2 to 2hr. 15mins on my N4 with typical phone usage as you. So the N5 is basically getting better battery performance then the N4. :good:

[TUT] Extending Battery Life

So our phone has a lithium Ion battery right? Well heres some things most people do not know about this type of battery.
Sorry if this has been posted before!
Li-ion batteries begin to degrade as soon as they start to be used.
One cycle is based on a 100% depth of discharge (e.g. discharging from full to empty), the potential number of charges can be increased by not allowing the battery to become fully discharged before topping it up. For example, allowing a fully charged battery rated at 500 cycles to drop to 50% before recharging could potentially triple the number of charge/discharge cycles to 1500 before the battery capacity degrades, thus increasing the batteries overall lifespan. However, this also means the battery will need to be plugged in more regularly.​
This means that keeping the phone topped up, and not waiting for full discharges will potentially extend the battery life of the phone.
In no way am i saying this a definite thing, as i do not know, and this wont extend your screen on time if that's what your after, it will offer you the same amount of screen on time, for an extended period of time.
So to conclude, charging little and often can extend the life of your battery. In theory anyways. I read up on this from a few articles and websites, too many to reference, but this is the combined knowledge i found.
There are still a lot of people who thinks that you must discharge to empty.
This was required when NiCd batteries were in use. Li-Ion are different.
Thanks for posting that! :highfive:
I have read on Note 3 forums how people cry about their battery life.
Thwir new software upgrade lowered thwir screen ON time to "only" 4-5 hours from 6-7. Whereby I am more then happy if i get 2-3 hours of screen time.
It makes me question my battery and software...

Friend, I wrote it looking at the topic of the thread. Hope this will help people who are looking to optimise their battery by tweaking some settings in CM 11.
At least helpful to those who have subscribed to this thread !
@sPEADy and @prem911 what ROM + kernel combos are you guys using ? :good:
@sprite048 I am using the nightly form 07th January.......and all defualt CM did'nt change anything
best battery saving strategy:
1) turn off wifi and 3g
2) put down your phone and pick up a book to read
3) dont touch you phone, use the landline to make call and laptop for messaging
right, speady?
Just kidding, WiFi and 3G are actually your battery killer. I'm currently using CM11 and can have 3 hours light gaming (Plague Inc.) with 700MHz CPU and 200MHz GPU settings. Another tip is dont use background process (such as news, email or even swiftkey; Google location accessing as well), they do wake your phone up regularly to sense if you have connection with the Internet Lord.

What is your average battery temp at idle?

Just wanted to know what people were getting in terms of temperature, i've not had the greatest of experiences with battery life with my Z1 although i know that some people have had great battery life, trying to get to the bottom of it and this is one of the things i'd like to know.

Possibly the BEST Screen On Time ever?

I've own the note 9 since it's release, and I've heard that the phones need to "calibrate" themselves to achieve their best battery life, so long story short, today I got this INSANE SOT
Pretty much an hour of SOT per every 10% of battery.
NO battery saving mode.
My screen is at WQHD
AOD off (I don't really need it)
Mostly WIFI
I'm using Swift Installer (all black with accents)
IMO I think this battery is an absolute beast. What do you guys thinks?
And yes, this was on a single charge. From 100% down to 4%
Did you check if anyone got better
