Battery Save Like RandomKing
I find myself regularly repeating many of these suggestions on many threads to many different people on how to extend your battery life. When not in use, my phone loses at most only 1-2% battery per hour! So I'm making one thread in the Epic forums dedicated to maximizing battery life while trying to explain why these steps will work. Some battery improvements come at the cost of performance or lack of certain services. This must be distinctly understood, or nothing wonderful can come of these steps.
Step 1: Brightness & Battery
Let's face it. Our Android phone screens are huge. This feature is the largest, and completely unavoidable battery-drain. The only way to limit it is to not use the screen... ergo... not use your phone. But that clearly makes no sense, so how to limit that drain? Well, a good step is to turn down your screen's brightness to the lowest you can read clearly, don't hurt your eyes! For night-time use, there's an app that can turn the brightness down even lower called Screen Filter(Thanks to iModMM for the find!). Also, choose a nice dark background, something in the black color range. For all phones, the darker the color, the less brightness used, less power consumed! But for our Epic's Super Amoled screen, specifically, a black pixel is technically an "off" pixel. That's right, every black pixel on your screen is a part of your screen not being powered, since the Super Amoled does not need backlighting. Blackle is also a good alternative to the standard Google site for a black themed search engine, though it doesn't seem to be mobile optimized. Also, lock your screen with that nice little button on the top right side of your phone. Don't wait for it to lock itself! As far as the battery itself goes, charging to 100% can be tricky. The moment that led turns blue, your phone has generally reached 100%, but it will generally trickle charge between 97 and 100 after that. A good way to charge to 100 percent is to use an external charger, which generally come with 1 or 2 spare batteries for about $20. This way, the moment your battery dies, shut down, and pop a fresh one in.
Step 2: Using a Custom Rom
At this point, there are many Epic 4G custom roms out, and if you're in this forum, you've likely rooted or are trying to root. Well I will not go into rooting directions here. Take a look at one and see how it fare's out-of-the-box for you. If you choose to use my customized rom, you will find a task manager with a preset ignore list, ready to use as a one-tap app-closing widget; as well as the service-freezing patch mentioned below in Step 8 ready for execution through a terminal, and my entire setup(among many other mods, apps, and tweaks tested for the greatest battery performance). These are just roms I've used myself to great results. Many others exist. Updated 7/6:
RandomKing's Customized Rom
2.2.1 EC05 v.1 Plus [Journaled w/Genocide 1.0] [Screenshots]
SyndicateFrozen Rom
2.2.1 EC05 v.1.2
Bonsai Rom
2.2.1 EC05 v.4.1.1 Not Supported on XDA. Sorry.
Midnight Rom
2.2.1 EC05 v.5.3
Step 3: Disable Unnecessary Services
First and foremost, disable all location services, wifi and gps based. This will affect certain apps like weather apps, you'll simply have to deal with static locations. Next, disable data sync. Contacts will not synchronize with Gmail while this is off. You will have to enable it sporadically. The Gmail app also will not function while this is off, I recommend using the email app and simply adjusting the refresh interval. You can always manually check your own email . Likewise, you may put your phone into airplane mode altogether if you don't plan to use it for an extended period of time, such as school, work, swim meet, movies, or on an airplane.
Step 4: Task Killers and JuiceDefender
First, let's get JuiceDefender out of the way. It's a neat app, and in certain ways, effective. However, it's own effectiveness comes with certain contradictions. It disables nearly all signals, which will include, for example, Google Voice. In my experience, this app hindered certain other services, and if anything may have drawn further on my battery. My recommendation is to stay away from it. Now onto Task Killers, they are good, and they are evil. Let me explain. Many of us may find issues closing all the apps we open, and sometimes forget we left something open. A task killer can easily ensure that you've closed all of your programs. Now onto the bad. Task killers can try to kill certain system services. This is generally BAD. Certain services shouldn't be killed, and others can't be killed, and the ongoing battle only further drains your battery while trying to kill services that AREN'T actually bad. So on that note, the worst part of task killers is AUTO-KILL. Disable it! Kill it! Kill it with FIRE! I use Advanced or Adao Task Killer, with no auto-kill. It is one of the only widgets I use, and I simply tap it before I lock my phone each time.
Step 5: Widgets
If you don't need them, don't use them. Almost all widgets make continuous unnecessary calls to the Android system, and this can be a huge battery draw. Even simple widgets. Through all my testing, there's only 2 widgets I have approved thus far: Advanced Task Killer, Power Control. Other disapproved widgets: Pandora, Winamp, Weather(ALL OF THEM), etc.
Step 6: SetCpu, Voltage Control, and Over/Underclocking
As with much of this thread, this is opinionated and empirical theories. Through my testing, Overclocking is unnecessary, and guaranteed to draw on the battery. Most of these roms come from fantastic devs and are, by default, blazingly fast. Overclocking is completely redundant in my opinion, and I'm generally all about speed. Underclocking/undervolting may preserve more battery, but my opinion on the matter is similar to my feeling on widgets. If you don't need it, don't do it. If you feel the need to use these apps, a generally accepted setting for battery preservation is to undervolt to 800 max. and 100 min. (if your phone can handle it, some may experience wake-locks, raise min. to 200) on conservative governor, adjusting your profiles for when the phone is locked, unlocked and etc.
Step 7: Unnecessary Apps
Free apps are great, aren't they? But how many have you gathered, just because they're free? Now how many of those don't you use, but regularly draw on your phone regardless. There's an easy way to roughly check. Open your settings. Now go to Applications. Manage Applications. Take a look at which are running that you have not opened. Using a task killer prior, and waiting a couple minutes to see what re-opens may be a good way to check which apps are continuously running in the background and evaluate if they can be removed.
Facebook --- Notorious for running in the background. Disabling notifications may help.
Latitude --- Largest offender of location service usage. Neat app. Huge battery hog.
QIK/Fring --- Any video chatter really. If you don't use them, remove or disable them.
Browser --- Large ram usage. Try Dolphin Mini or Miren.
Step 8: Freeze Services
Using Titanium Backup Pro, MyBackup Pro, or Bloat Freezer (yes, non-free apps) freeze any of the following services:
sns --- (Will disable sns)
snsaccount --- (Will disable Facebook contact integration)
drm --- (May affect media programs like mediahub)
drmcontent --- (May affect media programs like mediahub)
systemupdater --- (Best disabled if on custom rom)
Enter the following commands into the Android Terminal to manually freeze the above services:
Code:
su
pm disable com.sec.android.providers.drm
pm disable com.sec.android.app.sns
pm disable com.samsung
Simply enter the previous commands into the Android Terminal while substituting "enable" for "disable" to manually defrost these.
If you would like a shortcut for this method, check out the patch in This Thread Also Included In RandomKing's Rom..
Step 9: Journaling
Journaling... some love it, some hate it. The fact remains, journaling enables extra write cycles. While this will prevent data loss, it also means more cpu usage. It follows that battery should last longer with journaling disabled. You can use chris41g's mod HERE to turn Journaling on/off at will.
Step 10: Turn it Off and Spend Time With Loved Ones
That's right. You're obsessing with your phone. Leave it be. Do something meaningful and memorable. Have fun with life! This is just a phone.
More coming as it comes to me! Including mods, apps, etc. aimed at improving battery life. Feel free to leave your own suggestions or questions! If this guide and it's features have helped you in anyway, leave THANKS so I know whether or not to keep up on it!
Y is this in q&a?

has anyone noticed an effect on the phone's ability to sleep when you manually reorder the apps alphabetically in the app drawer? I kept having problems and factory reset 2x. Now I did find 3 troublesome apps that although not apparently running in the background, kept my phone from sleeping simply by being installed. I also stopped ordering my apps, deleted the troublesome apps and now it seems my phone is working correctly. I wonder if that (editing the default order) could also prevent the phone from sleeping? Any thoughts?

I'm non rooted stock EC05. I used to use EDIT in the app drawer to rearrange my apps in alphabetical order (they don't arrange themselves automatically this way after rebooting). I had noticed in spare parts that my phone was never sleeping and killing my battery. I did a factory reset and it worked as advertised. I slowly added apps back until I found two that seem to prevent my phone from sleeping so I uninstalled them. Phone worked fine for a while but then started acting up again. I repeated the procedure, leaving only the apps my wife's phone had (hers always sleeps like a baby), but then my phone started up again. Tried another reset but this time decided to leave the apps in the order they put themselves and so far so good...wondering if that was doing something or if it is an app update that goes bonkers?

Hmm. If you can't narrow it down to a certain app, I'm not totally sure what it could be. Have you tried clearing the data/cache of Twlauncher? You could try a launcher like LauncherPro, you don't have to be rooted to use a different one.
No but if the problem comes back up I will try some of those...these are the 3 apps that when loaded caused problems: NIV Bible, Document Scanner, [I now have relacement apps for each of these now] and most recently Espn Score Center, but my wife had all of thse but the doc scanner and had no problems
i would check in spare parts to see which apps may be holding a partial wake lock. for me the facebook app was not letting my phone sleep until i disable all of its notifications.

Likewise. This is why I removed facebook altogether. The new mobile site has proven to be pretty useful now.

Yeah I found the same thing...but I would log out of Facebook too. Also the problem reappeared after a factory reset and I had not gone into Facebook. Are you saying that even if you don't log in, it can stop your phone from sleeping? My phone started doing it again a few days ago for no apparent reason, and I was able to stop that behavior by: finding and moving 2 apps from the phone to SD card (I thought I had gotten all of them), clearing any cache from different apps, and rebooting.

That wouldn't tell me anything when I had the problem. The only thing was Android System....and....the phone wouldn't sleep even if in airplane mode! Which meant it had to be a process or app doing it all the time. I had never thought to clear cache, but I wonder why doing that works? Also there's a menu option in Spare Parts about Button Behavior which leads you to believe you can make the phone sleep but the menu says "only available in Ver 1.5". I've checked the market and can't find a ver 1.5 Spare Parts...

I believe it means android 1.5, because that says "End Button Behavior", and no new phones have Call and End buttons on them. Because the "Fancy Screen Rotation" says 1.5 only also.

I think you mean "Now go to Applications. Running Services." Going to Manage Applications will show all non-system applications and not tell you what is currently running, AFAICT.
Or am I mistaken?

No, there is a "Running" tab inside Manage Applications. An app doesn't have to have a service to be running.

Sounds to me like a system process may be the cause rather than any particular application. For me also I had issues early on with the SNS service forcing itself to restart continually and being a battery drain. It usually takes a force stop on that service followed by clearing data in the sns app and rebooting to fix. Don't know if that will work for you, but hope it helps.

My tips you can add:
1. I always, no matter what, always have brightness on lowest setting! If you have a hard time seeing in sun, than do auto, but turn off when don't need to, I have on low 24/7. Then at night, I have this app called screen filter which lets you lower brightness then default setting(good on eyes).
2. I always have auto-sync off. If you want emails etc. configure with ur preferences. And most of the time background data. But with background data off, you don't have access to market and have to enable for use. Don't get notifications. Lately, haven't been getting WhatsApp messages. This is optional.
3. In wifi settings, network notification turned off. Haptic feedback and all vibration disabled. Sounds on key clicks or anything disabled. Auto rotate screen off. No window animations. Screen timeout, 15 seconds. Keyboard timeout, 3 seconds. In location, use wireless networks and gps satellites unchecked.
4. No live wallpaper! No bright colors! I use a black background for wallpaper!! Try to go a little dark, not bright, stay away from white! Id recommened, the full black wallpaper. Also on ur homescreen, avoid widgets! Especially ones that use live web feed like, facebook, scorecenter. These are battery suckers!
5. I delete all apps I do not use! Stock and user. Download titanium backup to fix this issue. I freeze, system updates, swype, drm content, drm content launcher, sns, snsaccount. I uninstall the stock browser, use dolphin!! I also uninstall, all sprint bloatware, my files, gmail, email, talk, news and weather. Uninstall all stock and user apps you don't use! Check spare parts to see what runs in the background that you don't use. Another thing to add, I uninstall swype and android keyboard and use better keyboard gingebread edition 8.
6. Disable refresh interval in facebook, do it manually when you are going to use it!
7. Use setcpu. Undervolt to 800max and 100min on conservative governor. Set profiles, when phone is locked and etc.
8. Now lets talk about juicedefender and task killers. Juice defender will work and is a good app! BUT: if ur a person like me, I text a lot in whatsapp and when u lock screen it disables data, so u wont get texts. Download it, take a look at it, try it out. I recommend using agressive mode. Now lets talk about task killers. Personally, I think they dont work at all, and actually waste battery then save it. I just would say don't use one, and use samsungs stock task killer(actually works!)
9. Use a custom rom and kernel. Always be up to date on updates. I usually use, SRF and midNight. All about preference.
10. Extended battery FTW!!! Buy a seidio extened battery! May cost some money, but will greatly increase battery!!! Or get a cheap asian knockoff on ebay.
11. Disable data and put phone into airplane mode when it wont be in use for a period of time. Like at school or work. I usually keep data off during school. You will see a difference with data on and off.
12. Always keep wifi, bluetooth, gps, 4g off when not in use. They will drain battery crazy!!! Wifi will search for networks constantly, same basic thing with gps and bluetooth.
13. Also do full charges!! At night shut off phone and let it charge for a good 8 hours. Then in morning, turn on still plugged in. The charging indicator will be red, leave it alone till its blue. Go get dressed and eat some breakfast lol. Then when you come back it should be blue. And when on boot, let it finish media scanning, don't interrupt it!!
I can guarentee if you follow my tips, you will see a significant increase in battery life!
These are my tips!! I will add more if I can remember some more!
Typed this all on my Epic!!
I was wondering if there's any way to prevent android from killing programs immediately after i press the home button or switch to other programs.
For example, I'm browsing the Web when an sms comes in. Using home button (long pressing) I switch the task to answer and when I come back, the browser is gone and i have to load the page again (although it reloads in the same state).
It's really annoying. Reloading a webpage is not a problem but what about playing games?
I'm running InsertCoin 1.5, have about 80- 90MB RAM unused. And I doubt that I had RAM shortage
Thanks for reply
Your brought up that old horse (debate) on why the android OS does or does not need task managers. Yes, the wonderful engineers at android, developed a platform unlike windows, manages processes (by some opinions) way better than Windows. When you switch screens, it freezes the process, and holds it until you come back. When the phone starts to run out of allocated memory, it starts to kill the (less used) processes.
Now, I've heard of allocation of process levels to cause some apps to continuous run, which would be an interesting development for some dev to take on. You can select what apps you'll like to constantly run even if you switch screens. This would help those who would want to quickly drain their battery for OS calibration purposes.
If I find such a solution, ill report back.

Android should never kill the 2nd process in line (aka the Browser when switching to SMS), unless you're extremely short on RAM. In low RAM conditions, it will kill the farthest from recently used app in order to free up RAM.
How often do you notice this? is it always killing the app you switch from? Because this isn't correct (unless you're literally out of RAM as I said).

Like i said. I had plenty of free RAM. So it's unlikely that I have RAM shortage.
I spent the morning examined things. Just figured I it out:
Flash this over and I have 3 apps in line.
Combine with Perfect task switcher, I got what i wanted.
Also, I noticed that switching by long pressing HOME button and choosing apps cause the app to restart while using BACK button won't
I don't know if this is Android behavior or my device's issue
But anyway, I got it sorted out
Thanks you u guys
I'm running CM7. Long pressing home and switching between numerous apps I've never had an app close on me. Must be a ROM/device combination situation for you...
I have this annoying ''bug'' on the 2 custom roms I tried as well as the stock unrooted rom, sometimes I got up to 2 seconds of lag between the double tap thingy and the screen to wake up.
I don't remember having such lags with the M8 though I was using the Dot View cover double tap.
Why is the M9 doing this? Could it be too much apps working in the background? The infamous M9 wakelocks? Could it be the LP 5.0.2 memory leak?
It occurs once over 3 times perhaps, I always mocked old sammy phones to have this lag with the home button/screen wake and now we have this lag on the 2015 M9 :crying:

I have the same exect problem. Every time my phone is not used for a while i get massive lag on wake up guestures.
Did you find out what is cosing this lag?
Same here as well. It didn't happen on the M8.
If I kill all the recent apps it's a temporary fix, but it's not cool to do this before everytime we want to close the screen, it looks like a bad RAM management.
I hope someone can post this bug into Elevate so HTC fix ir

I think it has to do with RAM in general, I have the absolute bare bones on the ROM I use and I have issues with double tap to wake and even sometimes with the power button. I've noticed that the apps running option in settings doesn't accurately display how much RAM is actually being used. Just restarting the phone clears it up, but I have to do it once or twice a day.
Mine too peeps and I'm glad someone aired that one out ..personally it's annoying but not a deal breaker .I strongly feel it's a lollipop issue since google released multiple builds helping memory leaks and what nots
I dont believe it's a ram problem. The phone goes in deep sleep when you don't use it for a longer time. This you can see in the graph of your battery usage. This is normal behavior and saves alot of battery.
You'll see that standby time is way better when you don't check your phone every couple of minutes.
You don't have the lag if you try to double tap every or so minutes.
So ram problem is out the window. Or else you would be having it all the time?
And more importantly...you'll be having serious lag opening all of your apps.... Just check the s6 thread. ?
O.T.:Be careful crying ram problems or within no time there will be ram problem hysteria... (like camera hysteria,heat problem hysteria and so on...?)

If it was a ram problem don't you think you'll be having huge lags opening other apps? If ram runs out you will be seeing apps being closed when you open new big apps.... The only lag you notice is when waking the device when coming from deepsleep.
When it's running and you start opening apps you never run in to lag.
At least not on my phone.

Avoid them mate, the criteria for apps doesn't change with app killers, the start stop process actually uses more battery than it saves. Use auto starts mate.
I think the up threshold for screen off could be raised a bit to help with the lag, I can live with it tbh, haven't tried it yet.

Just my opinion sir, with no apps open and coming from a deep sleep I've only had a few issue. It comes more (for me) from multi tasking with multiple apps open for a prolonged period of time, turning screen off and then trying double tap or press power button on a minute or two later. I just wanted to know why the device thinks it has so much memory free. I should I have re worded my first post, I get what you are saying
I never experience this lag, but I did happen to recently have an occurrence. It happened when, by coincidence, I picked up my phone and double tapped right at the time my phone was receiving an email. Apparently being busy with a data process delayed the the screen waking. I'm just wondering if you all that are experiencing this issue have the phone set to turn of data during sleep mode and upon double tapping to wake an app waiting on data is beating the screen to the punch. Or maybe the act of data becoming active again is delaying the screen on. Just grasping at straws here, but it definitely sounds like something is interfering with the screen on process.
I didn't have any issue before the latest update but now it wakes too slow, even up to 4-5 seconds.

It comes more (for me) from multi tasking with multiple apps open for a prolonged period of time, turning screen off and then trying double tap or press power button on a minute or two later. I just wanted to know why the device thinks it has so much memory free. I should I have re worded my first post, I get what you are saying

My experience is more similar to Bubba Dub's here. There is almost always a slight delay in awaking with MLG or double tap, but every so often there is a multi-second delay and it almost always occurs after only a few minutes of inactivity and NOT after a deep sleep. It seems I'm most likely to experience the issue when I turn the screen off, then shortly thereafter go to wake with an MLG. I get the normal haptic feedback with my gesture, but the screen stays black for a second or two...long enough to make me wonder if I imagined the haptic...
I've found that turning off Auto Rotate seems to sort it out, though as soon as its re-enabled it happens again.
It's really annoying with a dotview case as sometimes there are massive delays when opening the flip, other times its instant and free RAM is always round 2.5-2gb due to custom rom and bloat removal. It happens on Stock, Stock Rooted, Custom Rom's

I turned auto-rotate off and just got the "big" delay (as opposed to the normal lag).
Hi All,
Anybody here with the same issue ?
Looks like a software issue/touch unresponsive issue because usually I find it coming back to normal once I press power button and unlock it again.
Sounds like RAM allocation issue, isn't ?
Thinking to sell it. Please suggest if you guys know a better way to deal with it !
Even if I go to SC, I cannot reproduce the issue at that particular time. They will just reset it and give me back, and that where I don't want to waste my time.
Does this looks fruitful to flash stock firmware again by the unbrick way ? I feel like that will be me last try.
You seem new here, so welcome on xda
One thing you should keep in mind is to be as precise as possible when presenting an issue, your description right now is not very clear, by the title it sounded like your phone actually froze, which could have been a ram or even a power management issue, but after reading your post it seems more likely that your display was wet, or that you were charging your phone, capacitive touchscreens are sensible to that.
Usually a frozen phone does not respond to the power button like yours did, and a ram issue seems very unlikely tbh

My style of using I believe is the same and I had no such issues in my Cool 1 ever in an year. Was a lot better in every way. Picked it up because I loved the looks, but have lost my trust on Huawei. They really need a lot of improvement.
i am having the same issues as the OP (Although i don't know what he means by "going to the SC")
the phone just goes through moments of extreme lag for about 10-30 seconds, sometimes longer, and it makes the phone COMPLETELY unusable during those times. it happens at least once every other day or so, sometimes several times a day, and sometimes it only lasts about 10 seconds, although on a few occasions, it has lasted several minutes, the phone will "attempt" to respond to inputs, but it gets nowhere quick, opening apps i did not click on, closing apps that weren't open, black-screening, half-screening (app on half the screen), etc.. sometimes i have to just power cycle..
i have the exact same feeling as the OP in that i want to sell the phone. (although i type much better, i'll assume english is a second language for him/her)
i like EMUI a lot.. although i think i want a galaxy s8/s9 now.

Since yours is the us variant, I'm assuming you've got 3 gb of ram instead of 4 gb, in which case a ram issue seems much more likely.
Not much of an issue actually, just that you probably had lots of apps open at the same time, leading to almost full ram (so the system starts closing background and even foreground apps if needed, leading to the strange behaviour you noticed).
Just remember to close apps you don't use and you'll be fine

It's 2018 and I think the OP and I know how smartphones work. I am coming from a phone with 2GB RAM and it has no such issues, no matter how many apps and/or games are open. Google explicitly states that closing background apps is unnecessary, and I should think EMUI offers an improvement over stock Android, not a detrimental experience. However, if you are correct and it is the RAM, it is not acceptable and needs to be fixed or I'm buying a new phone from a different company. In today's world, phones will open links to Chrome and from Chrome open reddit, xda app, pinterest, link to Facebook, share to Twitter, etc etc.. every time I click on a button I should not be having to back track to make sure I only have a certain amount of apps open. Nougat limits max open apps to 20 BTW, marshmallow it was 30.. But RAM management CPU management should be better. If it's of any interest, my reported "free" ram always stays at or above 1-1.5GB so I don't think its ram.. CPU or software problem, possibly.. But my Temps are good as well. Yes it's the 3GB version
Just a quick thought of something you could check (I also have the US 3GB version and was experiencing the same issue). Open up Settings > Battery, and other the "Other" section click "Consumption". See if there's any apps there that are keeping the phone awake and preventing it from sleeping. I would get constant lag after only a few hours of use, and it was intermittent just like you're experiencing. I was about to send the phone back, but checked this setting first. Turns out, the CNN app was running the CPU at nearly 100% for hours on end and preventing the phone from deep sleeping. Once I uninstalled that app, I haven't had issues since then. Could be something similar, just a thought. YMMV.
And by the way, it's NOT the ram. 3GB is plenty. You can see how much is being used on the app select screen, and I've never used more than 1.5 with a ton of apps in the background.
Let me help you there guys....i got the US variant too and has these freezing and lags all over the place, what i discover and did was:
1- Not all the apps works well with the phone hardware(they told me that somewhere) so try to test the apps you put on the phone.
2-Delete all the unnecessary apps from emui, that will give you less lag.
3-Check the battery consuming apps like the guy said and if you want turn on the close apps on screen lock.
Now after all of these my phone have been moving better but the problem isnt the ram, is the software so wait a little more so they can fix this cause is really a good value phone
It has to be the RAM management. Huawei must have optimized the software for 4GB, and then released a US 3GB version without changing anything, so it's screwed up even though phone is showing lots of free RAM.
Wao man thats the best explanation for this problem thanks man
It isn't and never was a RAM thing. Android's memory management essentially force closes apps (but shows them in recents) if it needs more memory. Note there is no work involved in that and you'd never know it until you switch apps and it has to reload, shows logo, etc. Amazing how non-solutions we're brought up multiple times and even thanked. Insert that's-not-how-any-of-this-works meme.

Well, yeah, ram issues nowadays should not be present, but I do speak on a basis, I have experienced bad performance and foreground apps getting killed on a nexus 5, which has 2 gb of ram and stock android. I have no idea what's emui's ram management policy, but on a scale, this would be the least likely cause for sure
I have had my P20 for about three month now... and it's OK but the Huawei "enhancements" and some other things are very frustrating.
1) Almost none of my "background" stuff works... Meaning things like Google Photo backup, SMS Backup & Restore scheduled backups, and other scheduled services don't run until I open the apps. Not much good to have automatic backups if they aren't automatic. Also, Google Rewards does not notify me of new surveys. Things that happen in the background seems to happen for a short time after you open the app, then they just stop.
2) Multitasking is a joke... On my old Moto G5+, I could have Facebook, Candy Crush Saga (don't judge, I have invested too much time to quit), Pandora, MeWe, Gmail, Messenger, Nine Mail, and a host of other apps running with no issues switching back and forth without them "reloading". On my P20 with the same RAM and supposedly a faster processor, if I am in Candy Crush Saga and switch to Facebook, then switch back, Candy Crush reloads when I was in the middle of level... Much less trying to have Pandora or a few other things going simultaneously. And yet I typically have 1.8-2.1GB of RAM available, it's impossible to actually multitask without apps restarting constantly.
3) Delayed or no notifications... From most apps... Gmail, Facebook, XDA, Nine (a real problem, this is my work email), Calendar, etc. Almost every app that isn't open gives delayed notification, sometimes a minute or two, sometimes hours, sometimes not until it is opened. Other times notifications show up, but no sound is given at all.
These things all seem to be related to how aggressive the memory and application management is to maintain the battery... Sort of making up for the hardware's inefficiencies through software. But it works, battery life is quite good.
4) Inability to change "default" apps like the Gallery... I hate the Gallery, but I love Google Photos as the "gallery" app. You can change it in the settings to the default, but few applications "honor" that setting. And for some reason the Gallery doesn't see all the photos I download with Photos. Weird... And even when you set other non-Huawei apps as defaults, it only works sometimes. This goes back to EMUI's software framework I think. Never had this issue on Motos, Nokias, Pixels, etc.
5) More of an annoyance than anything else, but what the heck is with the lock screen wallpaper? I can't get rid of the Huawei papers, they show up no matter what I do or how many of my own I add, the stock ones keep showing up. I have gone into the lock screen settings and disabled ALL of the embedded ones, and only my folder of about 50 or so images, and I keep getting the stock Huawei ones show up in the rotation.
Then there is the lockups... For example, open Google and search for something, switch to images, and maybe turn on GIF filter or something... This thing will grind to a halt in nothing flat, granted my old Moto would lag a bit, but it was 100 times better than this thing. I get the same thing in some apps but not others without consistency. Or if my UC-One app for work rings, sometimes it works, other times it locks up tight and needs a hard reboot to recover... No other phone out of the 80 or so at work does this. It's just so inconsistent.
And my last gripe is the data lag... At random times, regardless if on mobile data or WiFi, it will just lag out for 10 seconds to 2 minutes, usually once or twice a day, but not consistently... Everything looks fine, good signal strength regardless of source and other devices work fine, but no data will be moving and videos freeze and buffer, Facebook pictures don't load, etc. Granted, this really started after the May 2019 update.
It sounds like I hate this phone, but I do like a lot of things about it... The battery life if good, the charge times are good, the camera is excellent, the sound quality is acceptable, nice screen, not too big or overweight. But man, that new Pixel 3a XL at $20/month is sure looking pretty good.
Am I all alone here, or do others have the same issues?
Oh dude. 99 % of things you mentioned can be handled in the phone settings like telling phone not to shut apps in the background. You should Google before you write things down.
Ragarding your last point with lag: try doing a soft reset and install you carrier settings once again.
I've got the phone for half a year now and after searching and changing some settings it works better than anything else I've seen on a phone I paid 350 EUR for.

I take no offense from your comment, but I am not a noob... I have been working with Android since Eclair and smartphones in general much longer, including working on several ROM development teams and am an RC here. I did Google and DID turn off Huawei's "App Launch" management that I assume you are talking about trying to stop the optimizations from EMUI, and a few other things, but this is AFTER that. Although some of them seemed to help a little, it doesn't fix the problems.
Not only have I soft reset, I have done complete factory resets and all of my carrier settings are current... The lag also occurs on WiFi.
My post was kind of a rant, not necessarily looking for a solution unless there was one, and I was looking to see if I was the only one with these issues. Nor am I saying this isn't a good phone... Many of the things I have talked about would not bother many people.
In my case, I'm happy with the phone. Obviously I had some other problem, especially in some of the points you mentioned in the post. As the backup of Google Photos that did not work, but when I opened the app. However, selecting that all applications start manually has worked correctly for me.
I have disabled several applications using ADB. I know it does not erase them definitively, but hey, it's something. I also hate or just do not like the amount of applications that the phone has installed, I see them as unnecessary. I've always tried to use Google apps: calendar, dialer, calculator, clock, contacts, file manager, keep notes, etc. (that means I also disabled the original dialer).
But there is something that haunts me since I upgraded to EMUI 9. And it is a bug in recent applications that has a blue shadow that only appears when using a launcher. As I read, the solution is to disable the EMUI launcher, I did it once, but I prefer the appearance of recent applications of EMUI 9 than the previous ones. (Although I believe that this is poorly implemented).
Disable Huawei power genie app. I think it will solve all your problems with background apps.

The biggest issue is the wifi, very capricious
I have no problem watching a 1080p stream on twitch... but loading the newsfeed on FB, twitter, is sometimes impossible. I have to switch to 4g to load the newsfeed and it's very annoying ... Sometimes i can browse the internet for 5minutes, then nothing would load, for no reason ...
The battery management settings is also very aggressive, and notifications often displayed 1h, 2h late. Occasionally i get a "1 message from " " ... 1 day" on messenger app
One thing i really miss is viper4audio ... I did everything, i can't get this thing to work.
Appart from that, it's a good medium range phone.

I don't know what phone you have.I think you are on a wrong thread.This is for Huawei P20 which is a premium phone not a midrange phone.
It's not a 800€+ phone, and there's the p20 pro. I bought it for 379€ in europe, just a month after it's release. So for me it's more a medium range phone ^^ the top medium range

Thank you so much for this. I was so tired of having to reload recent apps. It was so bad on my phone that just switching between 2 apps would close the first.

Well,for me there are the specifications that make a phone premium/midrange or entry-level.The P20 has specifications that matches a premium 2018 phone.If you were so lucky to find a new P20 in spring 2018 for less than 400 euros,good for you.

You don't need to disable the Power Genius app, it can actually do some good... disabling it is functionally equivalent to going to Settings -> Battery -> App Launch and turning off "Manage All Automatically" and that will leave you like most other Android device with the kernel managing everything.
I disabled this at first after @costindaemon mentioned it, but Gmail app notifications, especially for non-Gmail accounts, got wonky... So I re-enabled Power Genius but turned it off as I stated above, then went through the apps and turned some on that I wanted "suppressed"... Gmail is an enigma here though, if it's management is turned off I had issues with notifications and accounts, and in App Launch it had a warning saying something like that, so I turned it on for that app and it's been good since. I have since just monitored the usage with GSAM's App Sucker and anything high on the battery usage list that I didn't want I turned on the Manage Automatically for that app and it no longer misbehaved. Think I have found the happy medium here.
I still have some issues with the phone, most just annoyances now... not to the level of frustration I was at before though. Still looking at that Pixel 3a XL though... it's in the cart, financing approved, but I just can't seem to pull the trigger yet. lol

You're right. I made a mistake in thinking that disabling power genie worked, when in reality it was just rebooting my phone that temporarily fixed the problem.
I did a bit of googling into a "ram leak" on the P20 and it was actually because I was using a 3rd party launcher (Nova). The solution was to disable the stock Huawei launcher, and since I did that 2 days ago my free ram has not gone below 1000mb. I've installed another launcher in case Nova mucks up.
But it looks like you've moved onto the 3a now, hopefully it's better than the awful software experience that comes with this phone xD. I definitely won't be buying Huawei in the future.

Yeah, I got my Pixel on Monday... Already think it's 10 times better, except the camera. That 2x "optical zoom" was damn nice although the Pixel's pictures seem a better quality even though they take longer to process. For the camera, I'm still giving the edge to the Pixel but I haven't played with it much yet.
All my issues are gone now and battery life is noticeably better. The Huawei will be going up on the local classified ad sites soon, hopefully the market for them isn't completely tanked.

Your lockscreen issue is solved by deleting the excess wallpapers from the lockscreen. As you cycle into the first one, tap it and...
Any issues you have don't exist for me. Likely because i always first disable/uninstall most major google apps immediately.
Any problems i've noticed don't appear to me as device specific but rather OS related. To me, this thing performs quite well with impressively low battery drain by comparison.
