Nexus 6 Battery - average or below average?

Today I took my phone off charge at 3.30pm, I'm on 50% with adaptive brightness off. My SOT is 2hrs 10mins, during which I've used WhatsApp, texted, used Chrome, played some music and YouTube videos, and played Temple Run for 20mins. I also have Facebook running, but I haven't used it. It's 7.45pm now, and my phone is at 51% with an estimated time of 5hrs remaining.
So that's 3.5hrs off charge, with about 2hrs SOT time, and I'm on 51%.
Does this sound average for the Nexus 6 or is my battery draining more so than normal?

That sounds way below average. I'm at 49% after 10 hours of heavy use. At least 2 hours internet and 45 min of talk time.

I have a super hard time believing that you had 10 hours of heavy use or we think heavy use are two different things.
To OP check out the battery life thread in general, could be a variety of rogue apps that are draining in background. If you don't turn things off I'm not surprised if you get around 4.5 hours of SOT

Is there a way to tell how many hours since charge? I just see that I have 12 hrs left

Yes, that is low in my opinion. On similar usage I typically get 6+ SOT 100% to 15%. Probably 75% WiFi, 25% LTE. Auto brightness.

This is about right. On my 3rd nexus 6 and they all exhibited the same behavior. I'm a heavy user as well and lucky if I get 5 hours sot. I had a short stint with a 6+ where I measured bit one day to give me a freakish 9.5hrs when I got down to 4%. I only hope things would get better for the battery as time passes. This is the perfect phone for me in every way except battery life.

You cant accurately measure SOT on iOS so I have a hard time believing this. I have several friends with the 6+ that barely get through the day here at my university, then again I can't vouch for what they do on their phones.

Believe me, on a holiday break without anything better to do you can easily measure it lol
Its incredible battery wise and may be as a phone if you ca stomache iOs, i couldnt.

What I'm staying is unless you have a stopwatch and can reproduce it accurately then it's hard to prove. I'm not necessarily saying your wrong, but it's hard to believe an iPhone is getting that kind of battery life, especially from what I have seen.
Now I'm not saying it's impossible but it's not something you see everyday. Its hard to measure something like SOT accurately without a built in system setting or app monitoring it. You can see why I have doubt's, but I appreciate you posting your experience.

This question makes no sense, as every battery thread. Battery is subjective, there is no such thing as "average" battery life. It all depends on how you use your phone and how your phone is set up. Everybody has their own kind of apps, setups, carriers.
The better signal strength you have in terms of carrier cellular data, the better battery you'll have.
Depending on what you do on your phone determines battery life. Yeah you can have 6+ hours SOT, but if you play games or watch videos then your battery life will be different from everybody else. Does that mean you have "poor" battery life? No, you just put your phone to more heavy tasks that consumed more battery life.
The way I see battery life, if I was able to end the day without my phone going down to 0% then it did its job. If I have problems with battery life, I'm only 15 minutes away from a quick Turbo Charge up to ~60% or get a portable charger if you don't have access to a wall outlet.

No offense taken at all. Quite the opposite, i completely inderstand where you're coming from. I have doubts myself when someone says they're heavy users on nexus 6 and get 8hrs sot. Everyones usage is pretty unique to them and can shift their sot numbers considerably to either side.
That being said and that i got that out of the way lol, what I meant when i said I had a lot of time on my hand is that i really had a lot of time towaste, that 9.5hrs was spent in one sitting believe or not. Most of it was binging on Netflix and the remainder was browsing on safari. I pretty much use my Nexus 6 the same way where its strictly split between Netflix/yiutube and chrome. Most if it on Wifi.
I didn't install any apps on top of stock in either phone except for google maps on iOS and adaway/titanium/greenify on nexus 6. I use the browser for everything else like facebook etc. And i dont play any games on my phones. May be my sot on the 6+ would've been different if my usage was different, but for my use case and setup the 6+ had the much better battery life.
However i ended up going back to the nexus 6 because its the better phone overall imo. I just need to find a way to improve the battery. I was hoping greenify would help a lot, but it didnt help much so far. My galaxy nexus had horrid battery life BUT the battery was replaceable and that made all the difference in the world, whuch this phone sadly lacks.

I see, thank you for clarifying your usage. If you want better battery life I recommend trying Franco kernel with Vomer Tweaks. I had 7.5 hours SOT with 25% battery left before I flashed a updated ROM and made a TWRP backup. I could have easily made it to 8.5-9hours SOT, however it was already 2300 and I didn't feel like staring at my screen until 0100 just to see if I could get more SOT. My phone was on all day since 0730 that morning, including time I used Bluetooth for GP music at the gym and some casting to my Nexus Player. Good battery life is possible but as you said everyone is different.

Wow that sounds impressive and really all that i need as sot goes. I'll def read up on how to do it and give it a try. Thanks for sharing!

Thanks for the replies guys.
Okay, so went to bed, phone was at 79% battery. This morning it was about 74% or so. Been on Chrome checking stuff, it's dropped to about 65% in half an hour. Screen brightness is around 30%. WiFi on, half cellular signal. I'm not doing anything intensive. My SoT so far is 1hr 40mins. Standby time is 12hrs.
So tl;dr - dropped 5% over 12hrs on standby, then 9% in half an hour with the screen on at 30% brightness using mainly Chrome.
I guess am just a little concerned in case I have a defective battery or something. I've alrady had one replacement already due to the camera arriving damaged.
What do you guys think?

Sounds about right. 9% in half an hour would give you 5 hrs SOT, and thats about average.
If you were doing Franko kernel with volmer tweaks that would be low. They do a lot to slow processor down and reduce capability to save battery, but you probably wouldn't be able to tell except for the occasional lag while scrolling a web page.

I get about 3.5-4 hours SOT. Seems fine to me. I don't do anything whatsoever to save battery. I keep the screen brightness how I like it.

Here is mine so far today. The reboot is from when I updated Franco kernel to r4. I used google play music at the gym and Bluetooth in my car driving to and from the gym and store. Battery life can be as good as you want it to be.
Edit: also I was only on WiFi for 40 minutes and LTE the rest of the time

Worried about Mi 5 battery life

I ordered this device yesterday but I worried about battery life, in reviews spoken the battery life was bad.
I dont have the device yet.
In the future the battery life was improvement on system updates?

I have to say I find the battery life to be outstanding if you are using the chinese rom. If using the global one it is really poor. There is another thread on here about battery life. Have a look at that

How much SOT on chinese rom?

http://forum.xda-developers.com/mi-5/how-to/discussion-xiami-mi-5-battery-life-t3338693

I look that but I Asks you.
Chinese rom was better than global on performance and camera?

In my opinion the chiense rom is much better although there are obviously some chinese apps there too

I'm reviewing the phone at the moment, my results on GeekBench 06:30:30 for runtime and a score of 3905 with the screen on maximum brightness. I've used the phone with dual-SIM and single-SIM and not struggled with it at all. MIUI 6.3.31 and it's the 64/3GB model. Hope that's of some help!

Battery life is usually good. SOT around 5 hrs for me and I usually play games.
However stand by is really odd one both the roms. Sometimes overnight it consumes 1%-3% sometime s 20%-25%, I still can't figure out why.

25% in night?? why?

Never seen that with mine. While at work during the day I only use it for the odd call and some texts along with a small amount of browsing. With the chinese rom I would have 85% charge left when I get home but with the global rom doing the same I would have about 65% left so clearly it wasnt going to sleep properly. Maybe thats what you are seeing

No, I haven't updated my signature from so long.
I have used nexus 5, galaxy s6(lost), lg g4 and oneplus 2 after Lg g2. For me galaxy s6 was the best device I have ever used.
Mi5 has a mediocre camera nothing exceptional about it xiaomi is creating hype about 4-axis and things however in reality it can't capture full hd video smoothly.
For sure Mi5 has better sound and battery and chipset but software wise I think any other phone out is better than this MIUI crap.
and believe me MIUI can never get fixed until and unless they changed their framework completely. As of now MIUI 7 is based on MM but it doesn't have a single feature of MM so what is the use of such OS. MIUI is for users who just want to keep applying themes and do nothing else.
I am never going to buy xiaomi again.
Hoping I get my hands on an AOSP or CM ROM soon or else I have to sell this ****.

I really don't know what is wrong but I experience the same on both the ROM's, yesterday I got 7.2.12 and after that it consumed only 3 % overnight even with alarm on.
Also, I have one more strange bug whenever I start playing coc my wifi gets disconnected and it gets disconnected randomly too, are you facing any such thing like this.

You have the wakelock qpnp_fg_memaccess that is draining battery. Check with wackelock detector..
Same happened to me one night from 40% to 6% in 6 hours..
This happened because Qualcomm introduced a new feature called Fuel Gauge that is managing the battery and is not working really like it should..

Strange.. I used my phone heavily(not gaming of course) and hardly to hit 70% in 8 hours during day time.

So what does one do about it? its my first day on mi5, i cant say that battery is bad.. its almost same as on a Sony Z5P.

My Mi5 is doing great on the battery... I use it at work i use it at home... during the night it drain around 5% max. Normally i can say it can last 1,5 days...
Using China Stable 7.3.3 With some battery usage tweaks..

Using CM13 I go all day without recharging from 7am to 7pm

Same here on CM 13 battery is good, lasting 2 days.

MI5 is one of the crazy device ever! Once you receive the phone you will be keep busy with experiment. Some people will tell battery life is outstanding and some like me will say battery life is poor.
My impression about MI5 is, usually after buying a phone we try to use it hassle free. But MI5 will create lots of confusion and make you trend to experiment lots of things until you get the perfection.
Currently the global ROM is most worst ever ROM and it will make you frustrated. Some people will tell China ROM is better but eventually until unless you are Chinese, you will never like chinese things!
Just now flashed CM13 and looks impressive!

The way you charge helps with endurance as well
Try getting into the habit of not letting your battery level drop below 15%. Charge it from there to 100%. Was a big item on xda some months ago about expanding the quality of a modern smartphones battery.

Is the battery as bad as the reviewers in YouTube are saying ? I want 6-7 SOT on normal usage.

I get 5-8h depending on what I am doing

I get around 7h SOT on normal usage with wifi on most of the time. Now I got 28% remaining and 5.5h SOT mostly on gaming/youtube. So I guess its not that bad

It's a card game, but it has some 3d elements and animations. It drains the battery 1-2%/5 minutes I think.
However, let me tell you this: I've been using Xiaomi Mi3 before (Snapdragon 800 and also 3000mAh battery) and Mi A2 lasts waaaay longer, so I assume some reviewers just look at the numbers and say the battery is weak

I'm in holiday in Bali and have been in 4G since arrival. I use the maps and Spotify for most of the day, play some light games and still have battery life to spare when we get back to the hotel at night.
The phone has great battery for me, but this is all opinions and your milage may vary. Not every has the same requirements for what great battery life is.

Not a good buy to battery life , only 4 sot to me .

I am switching from galaxy s8+. I am using galaxy with full qhd+ resolution almost full brightness.
Will Mi A2 battery work same as s8+?
Sent from my LG-V930 using Tapatalk

maybe the worst battery life phone i have used.
in 2018 getting 4Hrs sot is not acceptable from Xiaomi

For as long as people will care about looks then manufacturers will keep making super thin profile phones. If they made them a few mm bigger then could fit a bigger battery.
It's all about deciding what you value the most as you can't have everything your heart desires in one device. Just doesn't make business sense for a company to give you the best of everything at one time.

How much SOT do you get on a S9+? Its around 3-5h. How many times more does it cost? So 4-8h on a 250€ device is fine in my opinion.

I get 6-7 hours before battery reaches to 10 %. Mostly browsing, no games, wifi and 4G mixed.

I come from a s8+ with 5-6 SOT and with the xiaomi I have 5+ SOT, almost the same. Not bad for the price i think

I think 6-7 SOT is possible, depending on what you're doing. If you game a lot or watch loads of movies, then you're really stretching it though. I only got my phone last week, so I haven't tested it that much yet, but so far I can easily get through the day on one full charge.
But I don't play games or watch a lot of YouTube or movies on it. Mainly browsing, emailing, texting, phoning, podcasting, Spotify, a bit of Reddit, etc.
On the plus side, it charges really, really fast, but that's useless if you can't plug it in during the day. Besides that, the Snapdragon 660 is supposed to be more energy efficient than its predecessors. But if battery life is the main issue for you, then you might wanna reconsider buying this phone.
I would have preferred a (slightly) thicker Mi A2 with a larger battery though. 3000mAh really is the bare minimum these days. The phone is great, but it would have been awesome with a bigger battery.
Also, bear in mind, Android One takes up 13Gb of the storage size.

[OneUI 2.1] How big is the battery life improvement for you?

Although to a certain extent, we even came to doubt that Samsung would update the Galaxy S9 and Note 9 devices with the OneUI 2.1, it is finally here, and it cames with Deep Sleep Apps feature, which will allow to actually suspend all services and processes associated with an app.
This has resulted in a relatively big battery life improvement when the device is on standby with S10 and S20 devices in controlled tests1.
Galaxy S9, S9+ and Note 9 are devices released more than 2 years ago, and surely the battery stamina is not the same as they were in their first months of use. Samsung stats that the batteries used on these devices should keep a decent stamina for 2 years with the average user.
Some people have used their phones with battery care measures1, in order to extend battery life.
So, with the recent release of OneUI 2.1 for Samsung Galaxy Note 9, the battery life with the device in standby is expected to be longer (but not the screen on time), although the magnitude is yet to be determined in the coming days.
This thread is aimed to share our opinions on the subject, as the update becomes available and we can evaluate the battery life.

IOS uses a choise in his battery settings to charge the battery up to 80 % of it's capacity and then charging will stop to improve the battery's durability.
It's known that standing in battery's 20/80% capacity increases its life and durability and doing this you can charge how many times you want because one parzial charge will not be counted as an whole cycle of charge so the battery might last more than 3 years going on like this.
This choice is not implemented in Android even with one UI 2.1 and it's a shame even if the new feature will improve battery's autonomy due to the lower consumption of the apps and even if it's impossible to perfectly be able to stay in it's 20/80 percentage range, there's an app that I found that will avert you when reaching 80 % of its charging capacity so you can disconnect the cable to preserve the battery....

You're right and I keep charging between 30 and 80 but this shouldn't be how the phone charges by default as you said. Many people charge from 15 to 100 and want that extra 40-50% they'll get by doing so. I found that without fast charging it takes 1 hour from 30% to 80% so it's no big deal to look at the clock when you leave the phone on the charger.

Even your right, there are even people that continually from 0%(completely dead) goes to 100% after charging the battery for the whole night... that's why what I said for charging should be a choise (like in IOS) and not a default setting.... strange thing that Android or Samsung didn't consider implementing this choise. Fast charging even worns the battery first... it stresses the battery and it will last less but at least they gave us a choise in using it or not.

Absolutely true! Samsung should have implemented a feature to limit charge at 80%, or implement a Bixby Routine to enable this behavior (for example, when charger is plugged at night)

50% increase in my case. And i used OTA Package to update manually.
From: 4h SoT in 24h
To: 8h SoT in 24/30h
Idle times are impressive.
EDIT: just FYI, i rarely charge up to 100%. So my average case is from 85/90% to 5%. Very rarely do i go for a 100 to 0.
One UI 2.1 improvements are all courtesy of the Deep Sleep feature.
I've added everything i barely use or dont need to create wake-ups on the Deep Sleep list. On the normal sleep list, i have low priority things like Play store, etc. And i make sure i white list everything i need untouched (Messenger, WhatsApp, etc) and also do the same thing on the Memory management. Solid results.
Edit: 100% to 1%. 10h SoT with a 30h cycle. It's like getting better and better.

My tab a 2019 has the 80 percent feature and I do not understand why they wont offer the simple setting actually I do because phones they want you to replace the phone instead of the battery in 2 years. I run my note 9 from however low to 100 every night but only because I dont have the option these newer android 9 then 10 now 2.1 adding more and more apps into the firmware but wont add a simple little feature as this. Also I would like to be able to choose if I want to do ota with my data! But I cant.

For me One UI 2.0 was already worst with about 3 to 3.5 hrs of screen on time. Now with 2.1 i barely get close to 2 hrs of SoT. My note 9 is running stock since i bought it at launch and have never done any factory reset. Only thing i do is wipe the cache after a upgrade.

Bro you need to factory reset and start fresh and if that doesn't help something is wrong with your battery I get 9 SOT all the time with 10 2.0 with android 9 it was about 6 SOT, I haven't received 2.1 yet. I have us unlocked version.

You have a snapdragon variant which is anyway much better than exynos variant (my phone) for battery backup.

Stop saying Exynos is not good for battery life. I can easily get 8h SOT of regular usage on my SM-N960F running OneUI 2.1. Obviously I don't play games like Asphalt 9, etc but I never use power saving modes and never limit myself in order to save battery life. I play 8 Ball Pool when I want to, I watch YouTube for as long as I want to, I browse Instagram and use Samsung Internet Beta when I feel like it. Not once have I ended up in a dire need to recharge when I was outside or when I needed to use the phone. Also the phone charges 50% for 1h (I charge between 30 and 80%) so I just leave it charge while having dinner, watching TV or something like that - when I normally wouldn't use the phone anyway.

On my N9 seems battery life abit improve from previous 2.0. Sammy did great job this time.

Here is my screenshot to prove it.

It takes time to see improvement in your device's battery life after installing OneUI2.1. As the software AI needs to learn all your habits again before any improvement in battery life will occur. This process should take a few weeks

Question Battery life not lasting a day....

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.
BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours!
I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment.
Also, I installed accubattery which is not 100% reliable but compared it to my note 10+ and it seems that battery health is even lower that my Note (95%)! Which I've had for a year and a half!!!
What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.

Try disabling all power management.
In Developer options>standby apps all buckets should show as active otherwise power management is running.
Google Play Services, Backup Transport and Framework are known hogs.
Disable all the bloatware, turn off auto sync for gmail, turn off all feedback.
You'll need to sort it out and optimize it. Took me months to get my 10+ sorted out. Fortunately it's running on Pie so I had more diagnostic options.
Returning is a thought as 5G may have been poorly implemented and another source of power drain. I think everything after the 10+ 4G both hardware and OS are train wrecks... I see very little incentive to "upgrade".

Maybe post screenshots that aren't below 5 kilobytes. Lol. I'm guessing you have an Exynos variant?

It's too early to judge the battery life, also accu battery app is not good at all, it's not accurate as your own phone's batterymeter.
Also, you need a week or so to make sure the phone get optimised according to your usage.
Does your phone have Exynos 2100 or Snapdragon 888?

Mine has the Exynos 2100. I was just going off from videos like Mrwhosetheboss. He got 8 hours of screen on time. And he probably tested it when he got the phone no? And I'm litteraly getting half of that... and not even pushing my phone to the limit like he did on his video. I mainly use social media apps and YouTube.

I suggest doing a factory reset before you think about sending the phone back. Also, initially, be careful about what aps you install - try going with a minimal number of aps so you can get an idea of how the battery does when there are no aps that might pull from the battery - after a few days, add all of the aps you have been using (while avoiding any that might be a battery drain) and try for a few more days to see if you are seeing improved battery life. Good luck - hope it all works out for you.

Reloads -never- find the root cause and many times even if the problem is "fixed" it eventually returns.
Exceptions; old loads, software induced bootloops, viruses, and major firmware updates.
Expect issues with the 5G devices from poor hardware implementation. No fix for this.

I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

How much with screen off is it sucking down?
If more than 1% @ hr with AOD on it's probably Google and cloud crap running in the background.
You can optimize it to improve performance.
It's easier to do this with Pie though; Q and 11 take away critical tools and use scoped storage which wastes cpu cycles.
Get Karma Firewall and a package disabler like this one;

Regardless of the model or OS version most carrier phones will need to be optimized for good battery life and optimum performance.
My 10+ was a hot running bandwidth hungry hog until I toned it down. Today it's hard to believe it's that same machine.

You are right, I agree with all you said. It is kinda sad though, as for instance, my ex Asus Zenfone 7 Pro had an absolutely mindblowing battery life, without any tweaks. I just used it. With all the hype around the S21 Ultra, I believed it again. The only Samsung I used with good battery life was S20 FE 5G.
Will give it a go with what you say though, thanks.

Well, i believe what you are saying about battery life, but what i have seen so far is promising, i mean when S21 Ultra with Exynos 2100 beats iphone 11 Pro Max and 12 Pro Max, i guess that's a good sign!! But for sure, we use our phones in different way than each others because maybe you use it with 4G/5G enabled almost all the time while these tests are just using Wifi and maybe without any SIM card which means the battery consumption will be minimum at this part.
I have S20 Ultra with Snapdragon 865, i get like an average of 6 hours SoT and if S21 Ultra Exynos gives me the same SoT, i'll be happy!!

SOT is not everything...we travel, we move, you cant accept a phone that gives you 12 hours of standby in total. This is bs and useless, you cant rely on such a phone.

My AT&T 10+ was not real bad (or good) the first few days. After enabling power management it went to hell.
Eventually I disabled all power management and one by one tracked down the hogs.
Because of dependencies simply disabling and/or turning off say Google Transport and Google Framework isn't enough, firewall blocking Google Play Services* then clearing data on all 3 periodically finally stopped this hog dead in its tracks. These will run in the background when the screen is off stealing power for nothing. Sometimes the Google apks are misreported as other Google apks presumably because of the interlinking dependencies.
Try using Galaxy Labs Battery Tracker.
Developer options>running apks/cache can also yield clues. With an unrooted phone there's some serious game playing to track this garbage down.
Anything app that's cloud or carrier is bad... lol.
Disable all feedback and syncing except for texting; manually sync gmail.
*needs to be unblocked occasionally for gmail to download and for Playstore (another apk you should disable/firewall block when not using).

Try disabling 5G if you are not using it, for some ppl SmartThings drain a lot of battery but you should see that app in log. Can't wait to get mine, also E2100 and coming from Note 8. Was rly looking to have a 2 day phone.

That's a thought that's worth a try.
From what I've read even disabling 5G doesn't completely stop it's parasitic battery drain.
Maybe the latest generation chipsets are better but early 5G was poorly implemented giving a marginal speed increase on most phones of 20% when available.

Is this on the snapdragon or exynos variant?

So, 15% drain in 2.5 hours with nearly an hour of SOT. 15% is about 1/7 as a fraction. Now, 7 * 50 / 60 = 5.83 hours of SOT and 2.5 * 7 = 17.5 hours total. My Note 10+ (S20 Ultra on order!) doesn't do any better and NEVER did. If I use my phone for 6 hours a day (of SOT) it's pretty much done for.
I think people are being way too picky these days - just complaining to complain. If you really want I'm sure you can tune your phone so it gets 3 days on the battery. It'll suck and not do much of anything but, sure, you can do it. I've got a smartwatch and the same thing applies. I can tune it so it works for two weeks on the battery or I can actually use the thing and get 2-3 days. I choose 2-3 days and have stuff I want to use. I'd rather my phone be reactive and tell me when I've got emails, etc than to get super long battery life and basically have an inert brick in my pocket. I have a cellphone so I can use it for stuff. If that makes the battery not last long, oh well. If it can get 5-7 hours of screen time while also lasting through the day, great.

My 10+ draws roughly 1%@hr* with AOD on.
SOT draw varies between 9-12%@hr
Roughly 10%@hr watching vids on Samsung internet with surfing on Brave being the highest usage.
I consider it fairly optimized at this point.
*4300 mAh battery with little degradation.
No 5G running on Pie so not scoped storage either.
Figures are from a charge range of between roughly 40-65% as I rarely charged beyond 70% or discharge deeper than 30%.
Actual usage be more if I had started at 100% because of the power density difference through the power range ie 1% at 20 is far less watts than 1% at 100%.
A/V=watts. Less voltage means less overall mAh per % plus the additional losses due to voltage stepup power conversionas you dip towards 30% The closer to 100%, the higher the voltage with more available mAhs per battery% as well as less stepup voltage power converter losses.
A phone's wattage and V+'are constant so as the battery voltage decreases it draws more current ie mAhs.

You are also right, but , when you used something that does both keeping you up to date, and having a brilliant battery life, then it becomes disappointing when you change it for one that doesnt.
