Looks, its all down to what sort of experience you prefer.

If you want greater control over what can be done with your phone, go for Android. Just be aware that it has a number of quirks that are not easily resolved unless you're a techie. If you're willing to and know how to root it, you get a load of control over how your phone works.

And no, you don't lose updates by rooting. You just lose OFFICIAL updates but there's always custom roms like CyanogenMod and ParanoidAndroid that work quite well and have extra features to boot. More importantly - minus crapware like Samsung's Touchwiz.

If you want a phone that's easy to use and has a refined ecosystem, go for iPhone. However, I'm pretty sure you're well aware by now of just how restrictive the experience is as well - even when its jail-broken (which locks you out of future updates). Most ordinary phone users will never notice this nor care even so its fine for them.

No doubt, the reason why you are even considering the switch in the first place is because you are already fed up with the restrictions, in which case you shouldn't be listening to all those stupid fanboys asking you to stay. But like I said, do your research and be aware of just what you are getting into either cos you might not like it.

Incidentally, anybody who says Android is laggy is a non-techie. Meh to them.

As for battery, KitKat is lightweight and has incredible standby time. If you're not on KitKat, too bad. If you are but your battery drains quickly, than you're doing something wrong. My phone uses <1% per hour on standby.

Depends on their phone lar mang. Majority of Android users buy ~RM1k low to mid range, of course lag lar. If there's one thing that Android is doing wrong, its that the OS has a fair amount of bloat. This issue can generally be resolved by techies by tweaking the kernel.

Premium smartphones are fine.

KitKat seems to have resolved that somewhat but its not likely to trickle down to the lower end models so they have to hope there is a custom rom built for them. However, from this point forth even the lower end models will have decent performance.

I might be a droidfag and dislike Apple but even I don't simply go around pushing Android phones on other people either. I've already stated my phone buying guide once here and I'll repeat it again.

Richfag? -> Buy iPhone, unless you have some reason for considering Android.
Poorfag? -> Buy Lumia.
Super poorfag - > Buy nokia dumbphone lar bodo. No money still want smartphone.

Like I know someone who said iPhone screen too small. Complain eye strain just to read. Played with Note 2 at Samsung store and liked the big screen. Obvious choice there lar.
