Battery Life Guide - Worth a read if you are having issues.

Ive spent the last few days fiddling and testing stuff to increase battery life. Here is what i have learnt...
(Im running R2BA026)
Firstly, personally i do not want to lose any functionality/performance in order to gain battery life. I think that if you are going to spend the money to get a phone with awesome hardware it should be able to run at full whack.
This guide will not be useful to all, but hopefully it will be handy to those in my situation.
This is a guide for what i have found to be the best compromise between battery life and user experience, with the emphasis being on user experience.
My specific goals are:
- I do not want to lose any performance i.e cause any slowdown/choppiness.
- I am only looking for a 24h battery life as i can charge every night.
- I want to be able to use my phone without worrying about battery. Specifically I never want to think "i shouldnt do that it might run down my battery". I should be able to use all the features on my phone without questioning if i can afford to.
-=-
In my experience using a task killer resulted in only minimal gains to battery life but it meant that opening up apps could be a lot slower and apps could be choppy just after opening them.
Additionally the idea of setCPU is a good one however when coming out of sleep or opening an app it takes a little while to get back up to speed. This also causes choppiness. Personally I find lag/choppiness a real pet peeve, it irritates me alot, so I do not use setCPU either. It is true that with careful set up the lag can be minimised but then the battery life gains are also minimal, so I choose to keep full performance and dispense with setCPU. Bear in mind that the hardware platform is already very efficient and well optimised so a software solution will pretty much be a straight trade of performance for battery life.
-=-
With those two common options out of the way, what else can be done to save juice?
Well generally the biggest consumer of energy is the screen. The simplest option is just to turn it down to minimum brightness, but in my opinion that is not a good solution, its too nice a screen to have dimmed all the time. Thankfully the auto-brightness does a pretty good job of keeping the back light at a good level. It can be a bit disconcerting if you enable it when using full brightness as the drop can seem somewhat dramatic but don't let that put you off, give at 1/2 a day or so and you wont even notice.
Other easy but important things you can do are turning the screen timeout to minimum and always turning off the screen (power button) as soon as you are finished. They are tiny changes but really do make a big difference.
-=-
Onto wifi...
I think there may be a bug with the firmware because if I disable wifi I get a HUGE increase in battery life when Im at home. I have good 3g coverage here and a 3GB allowance so I only need to turn on wifi when Im browsing the web or market, seeing as it takes seconds with the widget this option suits me fine.
I suspect that when the phone is connected to wifi it doesn't sleep properly so drains very fast.
Only turning on wifi when i want it made by far the biggest difference to me, and as it doesn't affect my user experience in any appreciable way I am happy to do it.
I think its a good idea to mention app/widget updates and refreshes here, personally i have all my widgets and apps set to refresh only once a day, that suits me fine because I can refresh them all manually very easily if I want to to be absolutely up to date and I'm not a twitter or facebook addict Most of my widgets are news/article based so once a day is perfect.
-=-
GPS, again this is rather obvious, if you don't use it, turn it off. Personally i use latitude so I have it turned on all the time. Android seems very good about only using it when it is needed and the phone seems to get a fix very quickly so in reality it doesn't spend much of the day being active.
Same goes for bluetooth, although I don't use it so it stays off.
-=-
Nothing i have said here is particularly revelatory mostly common sense but I have always had battery issues often with the battery lasting ~12 hours before asking to be charged.
Updating to 026 made a big difference and following these rules means my battery drains on average 2-2.5% an hour under normal use.
Normal use for me:
-Wifi Off
-GPS on (With latitude widget)
-Gtalk always running
-3 news widgets + timescape
-frequent texting
-moderate calls
-frequent fiddling
The phone is very very snappy, everything apart from timescape opens as near to instant as makes no odds, the phone is a pleasure to use. My battery life has comfortably doubled without the use of any apps or any loss of performance.
Mission Accomplished

Thanks
Cheers for that. Very interesting .
I definitely agree about the task killer apps, the OS does a perfect job at running itself!
One question, Am i correct in presuming you have 3g always running? Network mode set to GSM/WCDMA preferred? Ive been afraid to do this as i have it in my head that 3g eats up my battery for fun! I'll have to try it out.
Thanks again!

I bought an extended battery for my X10 the sloping sides stop it looking like a brick. The G1 always looked like a brick with an extended battery but the X10 sloping sides do serve a purpose.

Yep, thats correct With the 3g on it seems to stay in 2g when sleeping then switch to 3g when you wake it, you can see the change in the status bar about a second after waking. Pure speculation though ...
Well, let us know how you get on with 3g active all the time

I love how slim the x10 is, that combined with the fact that the 3rd party backs are ugly and can be poor fitting mean an extended battery isnt really an option for me, whatever suits though ^^

Some additional tips based on my personal experience:
-Using a third-party task launcher helps too. Some may not agree, but it works for me.
-Use a third-party digital clock widget instead of the stock one. Again, YMMV.
-Use a third-party(AGAIN!) MP3 player instead of Mediascape. I'm using Meridian, and notice an increase in battery life when playing MP3s.

I like having some control so I run task killer but there's no auto-kill enabled and if I know the phone is just going to turn it back on in 5min, I don't bother killing those apps. Maybe I should just remove it altogether, but it seems convenient to be able to kill an app at will (I do it with windows sometimes).

I think the reason why you find that the stock one drains your battery is due to the "use network provided values" being checked in the date and time settings.

Interesting article. I am running 024 and my battery is life is poor. I managed to get seven hours use yesterday after a full charge. My usage throughout the day wasn't anything too crazy. Where I work I get only a standard signal (no 3G). I seem to get a better battery life.

I agree battery life is horrible. It makes me really miss my blackberry.
Even when battery life is low, charging it takes FOREVER, not to mention if you plug it in and play with it at the same time, it charges even slower.
My Blackberry Tour charged fully in what seemed like 45 mins from less than 10% batt life. I know they are different phones, but it just really sucks to me.
I'm debating going back to a blackberry now. The X10 and other android phones (and Iphone), are more toys than anything else.
/end rant.
hehe sorry

Thats odd, my phone charges pretty damn fast, just a few days ago i was pleasantly surprised that it charged from completely empty (id forgotten to charge it) to ~80% in less than an hour.

Hmm, mine charges from <10% to 100% within 1 - 2 hours.
Make sure you are charging by AC, charging by USB does indeed take forever.

Quite interesting for me, I decided to add some statistical experiment about it.
Under my situation and environment. (I won't go in detail, sorry about that)
With SetCPU were 2.32% per hour without any usage.
W/O SetCPU were 3.18% per hour without any usage.
or approximately 7% maximum saving per day time. (for me)
My SetCPU only effected sleep state.
Not a big deal but still significant different, but it could survive for whole day anyhow.
I'm more interested about Killing app. I might try after this as I see many argument about it.

Ohh figures, good stuff! Always better to have some numbers to work with.
Do you not find that for a few seconds after waking up the phone gets choppy?
I would definitely be interested in seeing the stats with a task killer

Do you guys leave internet/gps on or something? I get 3 hours/percent on idle.

Yup, with SetCPU for sleep state, it was 'choppy' for a few sec, mostly effect lock screen and screen switching.

Overheating

This thing gets hot! Just been configuring launcher pro which took around 5 minutes and wasn't data intensive and the back of the phone is really hot. So much that I can smell the plastic heating up! The battery drained real fast during the process too.
Anyone else experiencing this ?

Well that doesn't sound good! I haven't had anything like that. Have you checked the power intake?

Mine got really hot the first day I used it (27/4)...I was just checking out features and installing a few apps. I rebooted it after the battery was fully charged and it's been fine ever since.

I have the exact same problem, it happens especially when I play any games or intensive appliaction. The battery drains and it gets hot next to the camera, I suspect this is where the cpu lives. Do you think its because its rooted? because I rooted it as soon as I got it so I dont know what it was like before.
And as I am away from the uk for the next six weeks I cant even send it back to O2

No nothing to do with root, mine was same before and after, pretty normal to get hot on some demanding apps.

It gets really hot sometimes though, not to the extent of burnt plastic smell but it gets pretty uncomfortable touching around lens at the back.

I've been going through this this morning. It seems that the CPU loves to go up to 1.2GHz even if it doesn't need to be that high (and it stays there). Also there I've also been noticing through ADB shell that their are a few niggles. For example the wi-fi sharing process can start without even being activated.
For example this was a ADB shell top taken while running Cordy downclocked to 800MHz in setcpu. The phone was a tiny bit warm but only by the camera (where the CPU is). Basically, this just shows that if you are playing a game, nothing else is going on so the CPU shouldn't be going up to 1200MHz. And it plays the same as when it isn't underclocked.
I'm currently assisting Pulser with investigating this until he gets his SGS2.

If you do, freeze anything that mentions wifi sharing, unless you are going to use wifi hotspot and kies air a lot.

My phone got so hot that it shut itself down!
since that i have done a complete reset of the phone and started from scratch again....100% better.
The problem as i see it is with all the 'tinkering' that we users do. All the additional launchers etc and widgets that you add really seem to mess the phone up!
My advice is keep the phone as samsung intended it...or at least change very little. You will see far improved battery life and none of the over heating problems.
Just my opinion but its worked for me.

Find the nearest Apple store near you.

The only time i had this was when it waa both charging, in a case and playing a big game...
Im currently chatting, listening to a live stream, charging and posting this, no problem with heat at all..
Perhaps its a problem with some specific phones

that's just not true.
Mine gets hot aswell .. it's random sometimes but usualy with playing games etc. I suspect it has something to do with the samsung drivers/software and not our tinkering.
Bugs bugs bugs...

Mine also gets fairly hot, which might be a little uncomfortable - but that's the sacrifice you make when you get such a high powered device in such a small space.

Well,amount of apps/tinkering/etc has nothing to do with the phone getting got UNLESS an installed app in messing something up.I have heard many such cases when a rogue app made the CPU run at 100% in different phones.If that's the case you have to find and remove the app.I'd suggest OS monitor for finding it.Never happened to me though!
What's more,it's normal for it to get more hot than your average phone,as it carries more power under the hood and has nothing to help it dissipate the generated heat,as it's plastic.The Desire HD does a very good job with managing heat and I have never exceeded 40 C,even when gaming with an overclock at 1.8GHz and performance governor.Not saying the DHD is better,but Samsung wouldn't have left something like this if it would damage the phone.So I tend to believe that it's designed to get hot.

Mine has overheated twice.
Both times, when trying to pair itself automatically to my car kit. The phone got really really hot (i noticed it warming my leg in my jeans pocket) and needed the battery pulling out to reset it. When it started back up, the running temp was nearly 50 degrees (in standby, it runs at about 27)
Hasn't done it since though, just keeping my eye on it!

Strange Battery Issue

I've had my phone for about a week now(att unrooted) and experienced something very strange this morning. I fully charged the phone at around 5:30 last night and used he phone very moderately. At around 11:30 pm uploaded 3 photos on my google drive and the battery was 80-90%. Woke up this morning and the battery was dead. This is totally out of the ordinary because I never experienced this before even with my old and buggy captivate. Keep in mind that I was on wifi and the phone is not yet rooted. Has anyone else noticed anything like this?

That is strange. Honestly, I dunno what could cause it besides some random app that you installed.

i say download a battery calibrator and then go from there

Battery Calibrator won't do anything.
Install Better Battery Stats, and when your phone turns on after plugging it in, see what was using the most power. It won't work for the first time but will work in the future.

Even better uninstall ****ty apps and disable notifications on this like word with friends, scramble with friends, etc. Go into app manager and disable everything you don't use. Report back in a week.

I've had the phone for 5 days and gone through maybe 8 batt cycles. I'm not getting more than 2hrs screen time on any cycle. This is stupidly horrible battery life. There has got to be something severely wrong. I don't do much with the phone. I can't even with less than 2hrs to work with. Overnight batt loss is maybe 8%.
Any help is ENORMOUSLY appreciated.

Update
I was able to reproduce something similar. I opened up market\play to do a few updates and once the update process started, I put the phone down on my desk. Updates installed and the screen remained turned on. Now, I don't remember the exact steps or what other apps were running in the background. All I know is that the screen remained on for a few minutes until I manually turned it off.
This could very well be a bug in Samsung's face\image recognition software that handles smart stay. It might be a bug in google play, a faulty app or a combination of things... Because the battery on this phone is actually quite amazing. I unplugged my phone this morning, went to work, updated a bunch of apps, saved local maps to google maps, hung out on facebook, surfed the web... and after 10.5 hours, I still have more than 50% battery left.
That's a good indication that what I'm experiencing is a software glitch of some kind that if left un-attended, could completely drain your battery.

Try turning battery saver on and check pretty much everything in there. Disable smart stay. Manually turn off your screen when you're not using it. Turn off GPS, Bluetooth, and WiFi when you're not using it. Some downloads hang in the Play store if you "update all"... cancel these and download them one at a time. Do not just assume it all went to plan.
These tips on combination with my first post should help. You should get 4 hours of screen time with some phone calls in a single charge. I find certain apps like Scramble with friends chug charge faster than things like reading xda. Chrome for instance on the PC is less battery friendly and more resources intensive than IE. Perhaps the same is true for the mobile version.
There are way too many variables for us to pick out what your underlying issue may be. Start eliminating things and we'll keep throwing out new ideas. Good luck!

I have managed to narrow it down.
- I had 2 updates in market. I pressed update all.
- screen turned off when the first update was almost done.
- I pressed the power key and entered my pass to turn the screen on and left the phone on my desk.
- I kept seeing the smart stay icon, but the screen remained on.
- I moved phone without touching the screen...no change.
- held my hand over the camera at a distance of a few inches and the screen finally dimmed out.
This happened while google play had focus. This is a bug in smart stay or google play.

Somethings definitely up, this battery life is as bad if not worse than my epic 4g.
Did notice one thing... I cleared memory and it said 51 applications closed.... I don't even think i have that many applications on the phone!
Memory eats up a lot of power.

You're the second person I found that has the same problem as me! I can't even get 2hrs screen time through my day to day. The same day to day that my atrix was giving me 3.5hrs on.
I feel better knowing that I'm not doing something wrong, but could the phone just have that horrible of battery life and all these reports are a fanboi lie with review articles just copying each other?

I'm so glad im not the only one experiencing all of this! Lol, i upgraded from my mytouch 4G, i DID notice smart stay would come on at random times, sometimes when i wasnt even looking at my phone lol, disabled it & disabled a whole bunch of other crap & like many others & i dont get 4 hours screen time, more like 2 which sucks, id also like to have my data on all the time (but im forced to turn it off to save battery ), im rooted & ive uninstalled w.e crap i didnt need/want or felt it was just running for no reason. I'm doing the exact same battery steps i did with my mytouch & its sad =/ i was hoping i wouldnt have to do half of the ones im doing now, i LOVE my S3 but samsung needs to figure out wth is goin on & same with the guy who talked about if the articles r lying) i saw one on tech radar yesterday on battery life on the S3, they r either lying or they got a good phone in a good batch, smh, also experience my screen flickers from time to time while texting (i always close background processes) i notice blotches on the screen while texting at night or in the dark also, again i love my phone but u know, id love to have my data on constantly to check things quick without my battery going down drastically when i barely even touch it =/

I too have strange battery life. I usually leave my phone charging over night. When I unplug the battery in the morning, I lose about 10% every hour. However, when I get to around 80%, I recharge it again and it loses battery at a MUCH slower rate. Around 2% every hour on stand by. I'm not sure why this happens, but it does.
Also, there are some instances when I pick up the phone and it's pretty warm. Even though it's been sitting idle for about 20 min. Then there are times when I pick it up and it's normal room temperature. This leads me to believe that there are some processes going on while my phone is idle. I'm trying to find out what apps are causing this, as I believe it is causing my battery to drain while idle. It's very inconsistent, which is making it hard to track down. I don't even have a lot of apps installed. Most of it is actually the bloatware that came with my phone

I am starting to think it's ATT's LTE connection. I randomly have days where my battery won't make it until 5 pm without really using it very often. Other days, the phone goes all day with 4 hours plus of screen time no problem. On the really bad days, the phone will stay warm despite me closing every app with task manager. I am now experimenting with turning off mobile data (not a permanent solution), and the phone is cool to the touch again. It may be that the phone is burning up the battery in areas where the LTE connection is weak.

Mine did this as well I think it went up 3-4%.

Happy but Disappointed :(

I ordered the ZF2 from NewEgg when it released in the US.
I now had it for 4 days and generally feel good about the upgrade from a Nexus 5, but there are some things that really bother me with this phone:
1. Heat. This phone seems to heat up pretty bad when charging and doing something on the phone. When I just got it and was doing updates connected to power it actually gave out an error saying it overheated and needs to shut down.
2. Capacitive buttons are laggy. It takes about a second to register the press of the home button along with back and recent buttons. The Nexus 5 onscreen buttons so much faster.
3. The Zen Keyboard is laggy. Had to download and install the stock google keyboard.
4. Benchmarks are weak. Highest I got was 45k on Antutu. I have seen others getting over 48k. Its a minor gripe as the general performance is really good.
5. The plastic ridge that surrounds the screen seems to be very weak. It already has dings in it. Very sad about this.
6. Camera is not compatible with Hypwrlapse or ManualCamera app. I hope that those apps get updated and start supporting ZF2.
7. I don't know what's going on with this battery. Maybe its the apps that I have. But it feels weak. Woke up today at 8am. Its 5:30 now. I'm at 38% with 2 hours and 30 minutes screen on time.

1. Mine barely gets warm, and I have yet to see it get as warm as my G2 yet. It gets warm during charge but every device heats up during that process. Temps jump between 3x-4x℃.
2. I'm not having this issue, so not sure what the cause is.
3. The keyboard is smooth like the LG keyboard, and seems just as responsive as my N9 was.
4. I have the 2GB, so 42K seems to be the ceiling in antutu.
5. I've had mine for roughly a week and there aren't any signs of use on it, such as dings.
7. With my 2GB variant I reach ~2.5-3hrs for SOT at roughly 65-50%. I charge the battery to 85/80% and end up with 4-5hrs for SOT consistently. For me Android OS is really hurting battery performance.
"I'd Totally Hug You, If That Was Something I Did"

Something is seriously wrong with the battery of Zenfone 2, 550 ml. It automatically comes down to around 30% in 8-10 hours, even without any active use at all!

i was one who got early units of 550 ml...mines is performing very well......i dont have any issues too what so ever based on your reports above...standby time for 7 hours only reduce to 4 % batterry consumption for me....return your unit if its got warranty so you can sleep better

The battery and 5.0 are a problem. I've had wifi turned off for the past 3 days and the battery app is still reporting that wif is using 20-25% of the battery. The saving grace is standby which is outstanding. Left it off charge all night and it lost 8% in 11 hours. Once I start to use the phone the battery dies very quickly.

Do the rom upgrade

I have the ZF2 which I bought at initial launch from ASUS France. I can tell that I don't have all the issues you are reporting.
1. The phone does heat when charging or making lengthy calls but it doesn't bother me since while charging it's normal and I don't make as many long calls but this has not happened since the last FW update.
2. The buttons are working alright. I haven't noticed any lags. If anything they are more sensitive for me. Takes a screenshot every now and then if I hold my recent app key for a fraction of a second.
3. I always used Google KB on all my android devices so again can't tell but initially I was using the ASUS KB and didn't face any major issues.
4. I haven't done any benchmarks so can't report on that yet.
5. No dings whatsoever. I am also using a case so I barely touch the device.
6. The device has to be supported by devs. I know that the beta Microsoft Hyperlapse does not support it right now but it should do once they add support for it.
7. Well battery has been a concern for most on this forum but with the last FW I am getting 5 hours of SOT with 4G enabled all day. That's not bad at all compared to 2.5 or ~3 hours when I first started using the phone so it has been optimized and if ASUS is serious about this device (I hope they are) then it should only get better.

Had the same issue with the capacitive buttons, did a factory reset and cleared the cache and they are now pretty much instantaneous when you press them.

Go to Wi-Fi Advanced Settings and turn off "scanning always available". That will fix the Wi-Fi consistently on even when turned 'off'.

There's at least a few threads similar to this one already going in this device section. Like this one...

Don't need more the same. It just clutters the section and spreads the talk on the subject out between threads. Join the discussion in the one above, or another. :good:

Moto X pure battery problems

Im sorry if I do something wrong, I'm new at this. I have had my mxp for a while now and I never got great battery life but recently it has been terrible, when I unplug it I lose 5% in a couple minutes without even using it! I updated to Android 7.0 to see if that would help at all sadly it hasn't. I also turned wifi and Bluetooth scanning off and location is on battery saver. I haven't gotten 2 hours of sot in forever even with lite use, I swear I'm always plugged in. I included screenshots of my battery usage from an average day, is there anything I can do to fix/help it?
Thank you for your time

If you have poor standby time, and you have root you can try better battery stats. It should help you nail down if your phone isn't getting into deep sleep, and what is keeping it awake. Without root you can still get a feel for how much the device is awake by looking at the details you get when you touch the trend in Settings -> Battery.
You could try booting into safe mode and seeing if your battery life improves. That will disable everything but system apps. Do it by long pressing Power Off after holding the power button to bring up the power menu. It won't tell you what app is the problem, but it will let you know if you have a rogue app you installed causing battery drain.

Sorry but the images are broken!

My phone was at 48% and I restarted it and it turned back on with 5% battery any idea how that can happen? I rebooted it again to see if it was a mistake but came up as 4% I wish I could include the screenshot but I'm too new I guess.

Your battery is failing. Theres nothing other than a battery replacement.

My phone started doing this almost 4 month ago, when i updated to nougat. Normaly for me the problem is with the battery meter but not the battery. That means that the phone still have 46% and if you use it you will see the battery get stuck at 4%. Just don't restart your phone. Also after charging your phone power it off and on, if you see a jump in battery just keep charging and repeat the process until there is no change! There is a big chance that also your battery is almost dead but if you not add screenshots of your use there is no much more we can do for you!

I posted it in an other topic with simillar topic , it might be useful :
I had this weird problem with my battery too! MXPE on stock nougat , as soon as I charged my phone to 100% and plug out it used to drop below 80 in 2 minutes ! and then when the percentage hit ~20% It used to turn off showing that white screen you mentioned, however when I plugged the phone in it would start charging at ~15% ! so I tried recalibrating my battery and it is surprisingly effective !
here is the method:
1) drain your phone battery until it shuts down.
2)power it on again and you will see that white battery low picture. plug the charger for 3 or more seconds and out, it will boot up again but as soon as the Rom boots up the phone will die again . do it multiple times.
3)charge the phone while it is off until 100%. turn it on and drain the battery as fast as possible (max brightness, volume, streaming videos on cellular data and running benchmarks will do ) till the phone dies again.
4) repeat (2)
5) charge the phone up to 100% while it is off ! and there you go your battery is recalibrated and good to go!
Obviously, this will shorten the batteries lifespan but since I believe you have it for a long time It won't be an important matter!

Can you see these images?

Yes, it seems that your battery es dead. You can try one last thing if you want. Try to use the phone in safe mode and check how much Screen on time you got. To enter safe mode press the power button until the power off prompt appear. Then maintan the turn off pressed and the device will reboot to safe mode.

Better battery stats will work fine with non rooted phones you just have to run some commands in adb.

I tried safe mode and battery still drains super fast. What is Motorola's policy on replacing batteries or is there not one?

If the phone is under warranty they must replace your battery. If the phone isn't then you have to ask and see what happens and how much they will charge you.
Also it is not dificult to do it yourself. You will need a really good T4 screw driver, a heatgun, doble sided tape or a sticker to put the back agin. Finally a good battery replacement. You can search in the section for battery replacement and search youtube for tutorials. Good Luck with that!

Battery is now consistently dieing around 30 percent now, I think it's time for a new phone sadly.

Nearly a month now that battery dying at around 25-30% and hardly see the battery saver mode anymore. Also SOT hardly gets more then 1.5 hours so i think my battery life time is gone too.

Update: Strange behaviour today. After nearly a full charge got a auto power off some minutes after and when opened again it has gone directly at 3%
Will give it a try with a normal charger just to make sure the problem isnt with the turbo one!

Any suggestions for a replacement for my MXP? I'm looking at the $300 price range and headphone jack is a must!

Onward is the only way forward.

Moto X Pure Edition... 64GB edition . HTCs from that time period are said to be good all-around as well, but run even more expensive than the Pure Edition already does (and it seems to be holding its value somewhat better than expected). Personally, if my Pure Edition doesn't pull through, then I might just find another one, but the Nexus 6 has been a decent temporary replacement (aside from that screen).

Moto G5 Plus or G5S Plus... Or Honor 7x
To be honest, these are the only phones in the $200-$300 price range I would look at right now... Either will increase battery life 2-4 times, include SD card support, have a traditional headphone jack, and at least as much horsepower. Most other things like camera is a wash, the main drawback of any of these is they do not have NFC and sound quality can be a bit lacking, but few phones under $300 do with similar features.
A budget alternative (under $200) is the ZTE Axon 7 Mini at $169.99 from B&H Photo, it is an extremely under-rated device and although it is pushing just over a year old, it's features are hard to deny for the price, including NFC and truly amazing sound quality from both headphones and the stereo speakers. When this phone released it was $300.
TBH though, if I had to buy a device today and I had $200~$250 available... It would be the Honor 7x. Even pushing $350 to near $400, I would still go this route but once you hit $400 the choices I would make change a bit.

I have been looking at the Honor 7x and seems like a good phone, do you think the LG V20 is worth the extra 120$ over the 7x?

Honestly... I haven't liked LG devices since the G2 when I had a bad experience with it, but many people do like them... My issue here would be your paying ~$320 for a phone that is 15 months old, there isn't much argument about it's capabilities, most people like it. I would hop over to the XDA group for that device and read up some of the threads over the last view months and see what kind of issues people have been having, just silently skim for a bit and you will get a better feel for the device. On the good side it has a removable/replaceable battery, that would be a huge plus for this device. Your call on this one.
Personally, I just don't see the cost/benefit of most phones over $300 anymore... You can get a reasonable device for $200-$300 and in general to get much more you need to double or triple that amount now days but it isn't 2-3 times better.
