I've enjoyed my XT910 for a couple of years, but quit using it about 3-4 years ago. Now I want to use it with a secondary SIM, perhaps as a WiFi hotspot while roaming, but I find the speed appalling. Every operation takes seconds to show a result. Even unlocking to an SMS notification takes ~4 seconds.
Using MoKee 5.1 on a secondary ROM slot, I think. It's always on charge (as battery is slowly dying) and the only active app is PushBullet, used to see check my SMSs on other devices.
Does it make sense to invest in a new battery and keep this phone as my secondary? Or should I just get a cheap Chinese one, like Ulefone U007?
I don't expect miracles, just maybe using it as a light travel phone, mobile hotspot, speedcam notifier and occasional (once every two months) browsing. Should I maybe switch to a stock-based ROM that lives on the main slot? Get rid of slots altogether?
The phone lived some nice times, travelled around the world, edited and uploaded DSLR pictures with OTG, provided navigation to rickshaw drivers, was a portable desktop for a while, then a retro-gaming machine. Maybe it just wants to be retired...
Motomizer can help overclock it so it doesn't seem as slow. I haven't maxed mine out, just ramped it up about midway.

I've bought a new battery and installed Mokee 5.1, upgraded later to 6.0. Battery life is ok-ish, but not much of a difference. I've measured the old battery to still have 1400-1500Ah, the new one is ~1700mAh. I suspect the poor battery life was due to some hanging processes.
Anyway, with Mookee 6.0, the phone is unbearably slow. I have whatsapp, viber, google maps and nothing else. LMK has been set to very aggressive.
When I receive an SMS, it takes 5-15 seconds for it to load, if it doesn't FC. When I unlock the phone (after it sat for a while) it takes at least 10s to come to life.
My suspicion is that there is high memory usage (Android reports 30-70MB remaining) which causes everything to be evicted from RAM. Not sure what can be done, except install an older android version. I thought the newer ones had better memory and battery management.
Android OS - 285MB
Android System - 99MB
Google Play services - 75MB
System UI - 54MB
Phone - 36MB
Viber - 35MB
Messaging service - 35MB
Whatsapp - 33MB
.......
Free memory 28MB
Not sure what I should do: switch to an older Android version? if so, which ROM would be more responsive but still frugal? Do not update apps as newer ones eat more memory? Give up?
I've already half-given up and ordered a cheap Blackview A7, but I really liked the Moto as a travel/backup phone.

Yeah I read a post saying to do what you just described with success.
However, this phone is really poor. I have tried GB, ICS, JB and all of them I get similar performance just different features.
The phone can't handle two apps at once regardless of the rom.
I was traveling to a different city to get something on Craigs. It constantly would shutdown my Maps and Navigation when I wanted to read a Kik message.
If I have Kik open and want to read a txt msg, it takes like 10 seconds after clicking the txt msg icon to show the txt.
Is there an app or method that everyone uses on this phone that I don't know about to get this phone to run speedy? Or, is it just so outdated it can't run modern versions of apps?
I just want navigation, txt, kik, and a light browser like dolphin.
Can a Fascinate handle all that and be snappy and quick??
In the mean time, I am switching over to my S3, though I don't like how it's so big I can't reach all the screen with one hand.

i think you should understand that this phone has a single-core CPU. running at 1GHz. this phone is almost 4 years old. it's amazing this thing can even run things like Kitkat at all, let alone with the relative finesse the most recent unjust build provides.
it took me a while to realize that apps these days are not optimized for single-core CPUs, it took upgrading to a gs4 to realize that. the fascinate is an admittedly, well, slow phone. or its not meant for multitasking, definitely.
the s3 runs circles around this phone. almost anything does. i've never really found anything that allows for the multitasking and insane speed that i get out of my s4, the closest i've ever gotten was cm7, but that even in its stable release had tons of SOD problems (sleep of death, phone locks and never comes back on).
part of the issue is that the fascinate has 512MB of RAM. back in 2010, it was adequate. not even good, just.. alright. these days the norm is 2GB. a phone with 1GB of RAM is considered outdated. despite google's efforts to optimize kitkat for 512MB devices, this phone's GPU shares RAM with the system, and depending on the configuration, usually 100+ MB is reserved for the GPU, leaving typically about 360-384MB of RAM. You can get more (the kitkat ROM i've mentioned allows 416MB of RAM to the system) but things will start breaking, particularly HD video recording and torch, among other things

I have not used the kik so I can't really say about it's performance,,, I have seen on the 4.4 kitkat rom from Unjust when I have used google maps navigation it was a huge battery sucker, no matter if I only put it on device [gps] only. I could barely even use it and on a charge it was still draining it faster than it could take it.
i did not have this on jellybean roms
I have not had the the problems you describe '10 seconds to open an app'.
Hangouts used to be slow opening initially but their latest update has made it much faster
I don't think it's multitasking is bad for what it is as a phone given it's specs,,, but everyone use a phone differently,,,
so I mostly agree with the overall jest of what skept is saying,,, it is ultimately limited by the 512MB ram available to use.
for GB and JB roms you can also look at the V6 Supercharger thread, it does help with multi-tasking, it can be a bit hard to understand how to implement it but once you figure that out it goes decent, boot up and time till initial use are much longer than normal, but you just have to plan your reboots for when plenty of time allows
i think jellybean roms are very good performers and given the face that you can use a different kernel that allows for overclocking up 1400 Mhz if desired,,, it's a give and take though,,,, over 1200Mhz and battery life goes south very quickly. [luckily the battery doesn't take long to charge, usually 1 hour,,, and even 5 minutes here or 10 minutes there will really help it last through the day]
Most of the earlier jellybean [4.1.x] versions seemed to give better battery life from what I remember than the newer [4.2.x] ones
and there are a lot of different ones to choose from to suite your style or needs from basic cm to full customization.
most of them were stable enough to be daily drivers,,, the big thing is you will just have to read up on a particular one or just break down and try some to see if they fit what you want.
With all that said though the fascinate will never perform like an S3, S4, Nexus, Nexus 4, Moto G, Moto X
I would consider checking out the Motorola Moto G, it's physical dimensions are nearly she same as the fassy but a hugely better phone, screen size, etc and depending on your phone carrier needs it can be had for as little as $65 bucks...
Well lg optimus l3 is very powerful and performant in fact of multitasking if you're a dev or not a complete noob.My phone can go until 1.2 ghz without probs and its factory clock speed was 800 mhz.Most apps aren't optimized for multi-cores and l3 is single core.384 mb of ram are enough on stock and 301 mb aren't enough on cm.But my kernels got swap.
Battery is very good:10days in stand by,2 days in normal use.
Antutu sucks but i don't believe in it.
So its up to the devs,we're good devs and there are more than 100000 l3s in the world.Now we're getting dualboot.Its all about devs,its all about devs.

You're busy and don't have time to wait, which is why you need to stop reading this thread and get back to organizing your Pogs. Rate this thread to express how the Xiaomi Mi A1 performs when multitasking. A higher rating indicates that the Xiaomi Mi A1 keeps many apps in memory so that they don't need to reload, and that when moving between apps, transitions are smooth and performance is excellent.
Then, drop a comment if you have anything to add!
When I run Google play store in background, other apps in foreground starts not responding.
3.5 gigs of RAM are excellent (~0.5 gigs are left for the GPU). What I don't understand is that why this device employs a 512MB swap partition which causes wear and tear of its internal storage. I'm sure as hell this swap partition cannot be disabled without rooting which I'd love to avoid.
Actually it is very smooth in terms of multi-tasking
is it just me or anyone else experienced the same thing? my recent apps keep restarting even when i got about just 4 or 5 apps opened. i checked the ram usage but it seems normal, it uses about 60-70% of ram. does anyone know whats going on here?
What i have observed is, android OS and system, and few other Google apps take up 1.5+ Gigs of RAM. I am not quite satisfied with that...
However the performance and multitasking is very good though.

Restart your phone. Happens to me a lot on stock.
ability to use split screen for 2 apps is really nice.
Pretty much mid-range performance, as per expectation

Screen on Time 4-5hrs (~12% of use).
My Multitasking rating 3.5 / 5.
Pretty disappointing
Memory management is horrible in this phone..I have to restart the phone every 2 days.. otherwise the OS will keep killing background apps..even if u left any application to check a message or something, Android will instantly kill that app and you'll have to wait for it to reload again.. anything u were doing in that app is just gone ..I rooted my phone using magisk and uninstalled many bloatware like ant Hal services etc,..I use SD maid pro to clear caches, force closed every other app,tried to tweak the settings of the low memory killer, increased the size of the swap file even overclocked the phone to stay running at the max CPU ratio but nothing worked ..apps keeps getting closed the exact second u leave them despite having more than 2 gigs of free RAM
A1 just works fine for me
Is it just me, or does the phone use a lot of RAM? Mine seems to be using 2.7GB minimum at all times. Seems high.
Higher would be more ideal. The Windows mindset of "I'm running out of RAM!" doesn't get you anywhere here; in Android, empty RAM is wasted RAM. My Droid Turbo averages ~1.8gb used of 3gb. Seems Nougat tries to average 60%-70% usage.
When you switch out of an app, it's moved to the background and (usually) suspended, but kept in memory so you can switch back to it quickly. It's things like this that take up memory you think should be "free".
In the event that you need to load up a big app, stuff running in the background is quickly and gracefully unloaded.
Unless you're getting constant foreground app crashes - which might indicate that something is forcefully keeping itself loaded and starving everything else of needed memory - you shouldn't worry about it. Android is fairly good at handling memory these days.

I notice this issue more on custom ROMs than stock firmware. On mine and my wife's Quarks (3GB RAM, as you well know), running Marshmallow and Lollipop versions of the same ROM, something causes the phones to just freeze up for about a minute, crashes, then RAM is released to use. It was happening at least once a day on my phone, then my wife said it was happening to her phone. (Our old phones, not the new LG V30 phones.) I've messed with the LMK settings, trying different combinations, to no avail. And I did report it in the Nougat ROM thread for that phone. (Marshmallow ROM thread no longer has support.)
So, while I totally agree with your answer, it is the technically correct answer, I do understand the OP's concern. I've gotten to the point where I like to see more free RAM, so I know my phone isn't about to freeze up. At least on my old phone.
I love custom ROMs, but the past couple of weeks it's been nice to run stock on my new LG V30 and have a very fluid experience. I've not disabled anything. I saw some others disable stuff and then got lagging. I've not touched a thing and my phone is very smooth.
Could a "theme" downloaded from play store take up a lot of RAM and/or slow things down, too?
This is my first experience with a theme.

Possibly, but probably not. From what I've seen, LG themes seem to skin far less than say, substratum does, and even substratum is pretty lightweight unless you get into transparent themes.
Keep in mind the default theme is itself...well, a theme. You're not really saving anything by staying on it. If you see a skin you like, use it, if you're really worried use one of the LG-provided ones that come with the phone.

Interesting. It does seem like stock ROMs tend to be more conservative with RAM usage, whereas custom ROMs will have less aggressive minfree settings in order to keep more stuff loaded up. "Unused RAM is wasted RAM", but only up to a certain point; in my experience (Maserati with its ancient kernel as well as Quark) approaching ~100mb of free memory in LP/MM/N can bring things to a crawl, and pushing it can cause a kernel panic :good:
The only issue I've seen in Quark RR has been with the Pixiv app, though, and it does exactly what you said. But...I'm fairly certain the app itself leaks memory, as it only happens after browsing a while and is perfectly fine for another stretch after it OOMs and restarts.
My experience with stock ROMs in the past - Quark included - has been "smooth but lacking in features/customization" --- I've never really understood the complaints that stock is slow and claims that custom is blazing fast in comparison. The OEM has a decided advantage in that they have all the tools they need to compile the ROM properly, with then-current driver and kernel sources and a deep understanding of the hardware...I'd be really surprised to find a stock ROM from the last few years to be slower than custom.
But to be honest, my sample size is pretty small. *shrugs* I stick by what I've said, though, if anything the V30 doesn't use its memory enough; some people have complained about apps popping out of memory sooner than expected. LG is still putting out updates too, if a memory-management problem is found, hopefully they'll get right on fixing it.
Hello,
Since, two weeks now, my OnePlus X had a troubleshooting. The temperature of the phone is really high when I use it for simple task like browse the Internet (Chrome / Edge / Firfox) or Whatsapp, SMS, etc. And when I try to play at a simple game with no 3D stuff, it's almost impossible to hold it in hands. This is really really hot ! Battery at 42°C when I use any app like Whatsapp, Chrome/ Edge, etc. That's super hot !!
What's the problem ?
I'm on a custom ROM, the one of @psychem (Lineage OS 17.1). Before that I was on YumeMichi one. But the problem was already on that build.
I think the main reason for this is the battery. The phone's battery will get hotter after 1-2 years. It will run cooler if you change the battery.
I have the same problem but it's not because battery, my phone heats up at upper side of phone where the SOC is.
Me too, at upper side on AospExtended-v6.7-onyx-20200321-ROM. Not on RR-O-v6.2.1-20181124-onyx-UNOFFICIAL-fatal I used before :/
Me too.. this is on top of the top where the temperature is really hot !
I think I will be forced to change the phone for a Xiaomi Poco F2 Pro or, Mi 10 Lite or Realme X2 Pro. When I 'll have money ^^
OnePlus is not really the same company right now.
Same issue, since maybe 1-2 months now. Still running ResurrectionRemix 5.8.1 (Android 7.1.2).
I just replaced the battery (labeled 2015) by a new one (labeled 2019) and the issue is still mostly the same. The battery is obviously lasting longer now and doesn't drop steeply after falling below ~50% like the old one used to, but the SoC ist still heating up a lot in the top left corner of the phone.
Since you mentioned that you've tried LOS 17.1 and other ROMs by YumeMichi, I won't try to test other ROMs for now. If the issue is already present in different ROMs, I suspect it might have something to do with recently updated apps / frameworks, so maybe some Google apps or Google Play Services.
Looking at htop in root-mode termux (tsu) there seems to be a lot of CPU activity all the time, but not necessarily a super obvious culprit that's steadily using a lot of CPU. But I think I see a couple of GoogleQuicksearchBox processes appearing much more frequently than usual and some of my regular apps seem to start new processes a lot, as evidenced by the same app name frequently re-appearing under new PID numbers. It also it feels like I'm running into low memory a lot more now, because apps have to reload more frequently when I switch among them, especially Google Maps and apps that use the Maps API (like rideshare apps). So I suspect that something is causing apps to frequently close and start again, perhaps by using up too much memory.
Is anyone making similar observations?
How much battery, RAM, and CPU optimization matters on Android? Cause I'm getting 10hrs of screen on time on a 3700mAh battery.
So I have been using this Snapdragon 710 phone for over a year now and it's giving me at the very least 10h screen on time. ( Yes you read that right. 10 hrs on an average )
Things to note here -
• I don't use a SIM card
• My phone is constantly connected to a Wifi and a VPN
• I play games like FIFA or PES 40 minutes to an hour a day
• Rest of the time I browse Reddit, Insta, FB, watch Netflix and Youtube
• I do not use auto-sync and location
I recall using stock ROM (realMe UI) 8 months ago and it used to give me 6hrs of screen on time at best. Now that I'm using ROMs like Pixel Experience, RevengeOS, Oxygen OS, MSM Extended I get a much better battery backup. I don't close apps. Simply minimize them when not in use. My CPU always runs at a lower clock speed but the phone never slowed down or stuttered, thanks to 6GBs of RAM.
I went to stock ROM a few days earlier and used it for a week to check if I was wrong. Found out stock is still giving me 6hrs on an average which makes me wonder how much difference good software can make.
I do comprehend the fact that using a mobile network would cost some more juice. Then again, since I'm rooted I could use WakeBlock or Servicely to limit a lot of unnecessary background process that Play Services or apps like FB, Insta creates.
I'm sorry if it was poorly written. I hope you get what I'm saying. If you've ever encountered something like that please let me know. I saw people complaining about bad battery backup on phones with a 4500+ mAh battery. Can't phone companies do something about that?
