You can consider Sierra 760S, only warm although the battery life is slightly shorter

Works W/O battery too

is it OK to use 760s for heavy usage? i mean 24/7 on all the time..

MiFi is not mean for 24/7 bro

Never know this Sierra brand as local mostly using/selling Huawei
E589 really hot like baked potato when operating at battery mode.
i got AF23 but it's hot too, bleh the heat also transferred to my modem
most of the time using E5331, not really hot but most mifi's wifi signal very weak, no choice

if your mifi able to use without battery insert, then it might help to reduce a lot of heat,.. but i guess most huawei mifi can't do that for sure

Yup, most huawei mifi can't remove battery. The newer ones at least.

I am actually using e589 now and i use it 24/7 (at home and away as i am occasionally on the move) and there is no ill effects till date. I've been using it 24/7 since March 2013 fyi. It's never off lol. It can still last me a day. Didn't notice any degradation of the battery life. Maybe it's hard to notice with a 10 hours battery.

I've been using mifi's for a couple of years now (e585 > e5756 > e589) and it's always been abused daily by me.

I know that alot of sifus don't advice doing this but from my personal experience, there are no bad effects till date. I reckon that batteries have evolved alot since and we're also actually using batteries non stop daily already (on smartphones, tables etc) and it can lasts years before wearing out. Even old ipad batteries are going strong.

Last time i remember using a battery on laptop and it dies out within a year or so, and it last only 2 hours for new battries. Not anymore with newer generation batteries. Not to mention that new MBA batteries can last about 12 hours now lol. The evolution of batteries are amazing.

Nowadays I rarely use my USB modem, MiFi is far easier and when always ready when I need it.

As for performance differ, LTE standardize the performance unlike previously some modem faster on 3G some slower

operate on LTE will confirm get lower heat too compare to hog on 3G

Definitely so much better on 4g... for now

The upload speed and ping is what's a massive improvement for a better online experience.

We'll see how it handles congestion in the future. Hopefully that future is still far away

I kinda notice that the modem is not that hot on 4g when compared to 3g. I never did pay any real attention to it but this post kinda remind me about it.

E589's battery is embedded, can't remove at home i use E3276.
I was using E589 most of the time, though its quite hassle there is no way to turn it off remotely(android mobile wifi app can do that but i have yet to try it), yeah im lazy lol
second is, the E589 USB port does not support data transfer, it's just for charging only
third, after i upgraded to Windows 8, both of my wifi adapter will randomly disconnected, there are still no fix for this problem, unless use another pc to share the internet by using ICS, or using back windows 7

I think that probably your windows driver (wifi) should be updated to support win8, if there is an available update. Or is there really no fix for some reason?

I'm using win8 with no wifi issues here.

Was using TPlink 300mbps wifi adapter, tried different driver from stock to beta driver from TPlink itself also ssame, never knew the chip was made by Qualcomm Atheros it's version 3, version 4 using realtek chip already.
then i though their driver support was sloppy, bought second adapter from ASUS, made by Broadcom, even worst, after it disconnected from USB hub the adapter will not reconnected again
Both vendor also never provide new driver
it happen too frequently, too irritated by it then i reinstall w7 and viola, problem solved
now i rarely use usb wifi adapter anymore, my expensive asus wifi adapter now is as good as decorative blue LED
edit: just checked asus website, there are new drivers now, lemme tried that and will report back lol

That's one long story there. Feel sorry for you. But at least you got the problem was solved ady

What wifi adapter are you using? there are actually a lot of people have the same problem, even on windows 7
btw Broadcom wifi adapter seems have a lot of problem with its driver

Not using wifi adapter as i'm using a laptop. Don't use a desktop

Well Laptop still using a wifi chipset right?
Just wanna know which wifi chipset and your laptop model

Ah ok, i thought we were talking about the usb wifi adapters...

My laptop model is HP folio 13. How do i check my wifi chipset? I'm not too technical here lol ... but I'm using intel wifi driver, so probably it's intel?

Well there are a lot of mifi but i only know Huawei
the stock E355(portafi) also ok, if afraid overheat, just remove the cover but the LED is VERY bright at night lol
personally using E5331.

they are almost the same but with extra usb interface
Yeah i hear Intel one do not have problem with W8, Broadcom one seems have some problem with w7 too.
My laptop broadcom wifi will hang on linux OS , buggy piece of crap lol
next time buying lappy will look out for intel one
